False lily-of-the-valley (Speirantha gardenii) is one of our favorite early spring-flowering evergreen groundcovers for shade, but one that just hasn’t caught on with customers. Every time we put this back in production at Plant Delights, we wind up throwing out most of the crop. Perhaps one day, folks will realize what a gem this is. Hardiness is Zone 5b-8b.
Here is a clump of Calanthe ‘Takane’ in our garden in early April. This amazing and easy-to-grow terrestrial ground orchid forms a dazzling clump with age. This mass started as a single division in a 4″ pot, 17 years ago. Not only do they thrive in the ground, but in Japan, they are prized as container plants.
Calanthe ‘Takane’ is a group of hybrids between Calanthe sieboldii and Calanthes discolor, so each seedling is slightly different in flower color. The foliage remains evergreen during most winters for us, but when temperatures drop near 0 degrees F, the foliage will die back completely. Calanthes thrive best in light shade. Winter hardiness is Zone 7a-9a.
Here are images of three of the “next generation” ajuga cultivars, all selections of the Italian Ajuga tenorii. These in-ground photos were all taken at JLBG on April 1. These new ajugas don’t spread wildly or seed around like many of the older, more commonly grown offerings. We think they are pretty darn amazing! The top photo of Ajuga ‘Blueberry Muffin’ represents several plants, planted on 1′ centers. The second image is a single plant of Ajuga ‘Cordial Canary’, and the third is a single plant of Ajuga ‘Petite Parakeet’. These are actually non-staged images, unlike the highly staged, completely unrealistic, manufactured photos you often see in the Dutch-centric catalogs. Hardy from zone 4a to 9b.
It was great during our recent winter open house to see so many folks noticing the aucubas in the garden. Of course, they are hard to miss with our collection of over 140 different taxa. There are few evergreen plants better for year-round interest in dry shade than aucuba. Here is one of the most fascinating ones that’s in flower now in early March, Aucuba himalaica var. dolichophylla. This little-known, narrow-leaf species hails from 3,000′ elevation in several southern Chinese provinces. Winter hardiness Zone 7a-9b, and perhaps a bit colder.
Podocarpus macrophyllus ‘Okina’ is looking lovely this winter. This Japanese selection has resided at the base of a large pine tree at JLBG since 2001. We love the white speckled foilage, which really shines in the winter months. Podocarpus macrophyllus is one of a short list of conifers that thrives in the shade of a woodland garden. Our 20 year old plant is now 6′ tall. Hardiness is Zone 7b-10b.
A couple of weeks ago, we mentioned our landscaping project on the north side of Mt. Michelle to create more intricate planting pockets, while raising the planting heights significantly via the use of rock assisted berms.
Phase 2 of the project was to create a cut through on northwest side through a previously inaccessible bed. Phase 2 is now complete, and visitors can now traverse the new path, exiting into the northwest side of the Mt. Michelle waterfall. This path takes you under the large speckled-leaf loquat, Magnolia macclurei, and several large conifers, so be sure to look up as well as down.
Last week, Jeremy and his staff tackled phase 3 of the project, which was the two 50 degree slopes on the west side of Mt. Michelle. Despite being planted for some time, we had lost some soil due to runoff, and the plants were screaming for more compost, and we were screaming for more rock pockets.
In less than a week, Jeremy’s team stacked these new retaining planting walls, which provide hundreds of new planting pockets for small woodland treasures. Each is now filled with our garden compost mix as well as an array of small, little-known plants. Just remember, if you garden on flat ground and think you are out of planting space, the key is to learn to think like a Pythagorean…a² + b² = c²…go vertical.
You’ll be able to see these newly planted areas during our winter open house, although it will take a while for the plants to mature.
We treasure any plant that makes a great woodland groundcover, and are particularly smitten with the ophiopgon (mondo grass) and liriope (monkey grass) selections. We currently grow over 120 different ophiopogon accesions including quite a number of wild collections, at JLBG…see what a touch of OCD does for you. We’ve grown Ophiopogon ‘Comet’ since 1997, and love it for its white striped foliage and well-behaved growth habit. Hardiness is Zone 7b-10b.
Picea rubens (red spruce) is one of only 8 US native spruce species, and the only one whose natural ranges includes North Carolina. The entire range of red spruce starts in Nova Scotia and continues south to high elevations in the NC mountains. Genetic testing indicates that our red spruce evolved due to climate change during the Pleistocene (12,000 years to 2.5 million years ago), when it split off from Picea mariana (black spruce). Black spruce is now the only other nearby spruce, which currently resides from New Jersey north with a small population in Northern Kentucky.
Surprisingly, red spruce is virtually absent from piedmont gardens, probably due to the common wisdom that it doesn’t tolerated heat and humidity. As long as it’s given adequate amounts of Calcium (we aim for a pH of 6.5), it grows beautifully. Here is our 26 year old specimen, that didn’t get the memo that it’s shouldn’t grow here. Hardiness is Zone 3a-8a.
Red spruce wood is used to make high quality wood instruments like violins and acoustic guitars, but to avoid cutting down your lovely specimen, we recommend you stick with products that can be made from the foliage, like the infamous Red Spruce Beer.
The first plant looks for all the world like a fine textured carex, but in fact, it’s an iris. Iris dabashanensis is a little-known species from China, that thrives for us in light shade, but will also take a few hours of early morning sun. Our plant is a Darrell Probst collection from Sichuan, China. Winter hardiness is Zone 5a -8a.
Below is the same plant flowering in early April.
The other plant growing nearby in our gardens that fools even the keenest plantsmen is this liriope look-alike. In fact, this is a cast iron plant, Aspidistra linearifolia. This demonstrates why those pesky taxonomic traits matter. In 2008 we introduced a selection with a lighter central stripe down the center of each leaf called A. linearifolia ‘Skinny Dippin’ which we will be offering again in 2023. Winter hardiness is Zone 7b and warmer.
Most gardeners know the genus aspidistra (cast iron plant) from one or two species, and if that’s the case, you probably only know those which hold their leaves vertically upright. There are equally as many species with pendant leaves, which provide a completely different form in the woodland garden. Here are two of those pendant-leaf species from the garden this week.
The first is Aspidistra sichuanensis, which is one of the larger growing species. A single clump can easily spread to 6′ in width in a couple of decades. This clump has topped out at 3.5′ in height.
Below that is Aspidistra ebianensis ‘Flowing Fountains’. With narrower, wavier foliage, it makes a large clump, albeit slightly smaller than Aspidistra sichuanensis. Both plants are winter hardy from Zone 7b and south.
Below are more of the Ice n’ Roses snow roses flowering now in the gardens at JLBG. These amazing sterile hybrids were created in Germany by the Heuger plant breeding company. They have proven fabulous in our trials, but are still often difficult to find due to the screwy production cycle.
Because these snow roses, as Heuger calls them, are clonal and sterile, they can only be commercially produced by tissue culture, which is all done overseas. The non-rooted microplants are shipped in sterile containers to the US, where they are received at rooting stations (nurseries capable of putting roots on these microplants).
There are only three North American rooting stations used by Heuger, one in Canada, and one on each of the US coasts. Once the microplants have roots and have grown large enough, they are purchased by finish growers, who pot and grow them for 2-3 months before they are a saleable size.
For a finish grower or retail nursery to have plants available to sell in late winter or early spring, they would need to receive liners (small plants with roots) from the rooting stations in September/October. The problem is that these rooting stations usually get their unrooted microplants from overseas in fall, when their losses are less and the plants finish faster.
Consequently, these rooting stations only have plants available for the finish growers from February – April. This means that the finish grower and retailer will only have plants ready to sell at the beginning of summer, which is certainly not ideal unless you live in the northern tier of states or Canada.
The only option a finished grower has is to hold the plants through the summer and fall, to have them available in the late winter flowering season. This drives up the crop cost dramatically, since a nursery has an overhead cost per square foot per month of growing space. Until a change is dictated by the grower throughout the supply chain, it is unlikely that the supply will be able to keep up with the potential demand. Anyone think making plants available is easy?
Throughout the years, we’ve grown literally thousands…perhaps 10s of thousands of seedlings of the Japanese sacred lily, Rohdea japonica. Each one varies slightly, but we only save those at the far end of the bell curve. Here are three of our seedlings which well represent that dramatic variation at each end of the spectrum…a wide leaf form we named Rohdea ‘Stork Nest’ (15 yrs old), a very narrow leaf form we named Rohdea ‘Thin Man’ (16 years old), and a miniature that has yet to be named.
Fargesia robusta is one of the many excellent clumping bamboos for the garden. Thriving in light shade to part sun, this evergreen gem tops out around 7′ in height. We know it’s still hard for some people to realize, but clumping bamboos truly cannot run. This garden specimen at JLBG is now 22 years old. We love both the texture and architecture of bamboos. Winter hardiness is Zone 7a-8b.
Every year, we grow thousands of lenten roses from our own seed collections in the garden. Most, we sell at our Winter Open Nursery and Garden as Helleborus x hybridus ‘Winter Delights’. All of our Winter Delights hellebores are hand selected by color after they flower. Every now and then, an incredibly unique form gets pulled for the gardens and here is one of those from a few years ago. This amazing plant has huge 3.5″ wide flowers, and was already in full flower by January 1. We hope everyone can visit our upcoming Winter Open House and see the amazing hellebore selections in the garden.
We love the evergreen ruscus in garden, but realize they are a plant that will never be found at most mainstream garden centers. A genus of only 6 currently recognized species, native from Europe into Eurasia, these horticultural oddities are so odd that they once qualified to have their own plant family, Ruscaceae.
Now, with improved DNA testing, they were found to actually be members of the Asparagus family. Exactly where within the Asparagus family is still an ongoing debate. Within the last decade, they were grouped with Nolina and Dasylirion, which to those of us who work with live plants, made no sense. Most likely, they will wind up in their own section, but as distant cousins to better know genera like Rohdea and Liriope.
Ruscus are great evergreen plants for dry shade, in regions where they are winter hardy, which is usually Zone 7b and south. Ruscus are unique in that they don’t produce leaves, but instead have leaf like structures known as cladodes, from which the tiny flowers emerge. All ruscus species have both separate male and female plants, although there are four hermaphroditic (bi-sexual) cultivars of Ruscus aculeatus in commerce, which produce the lovely red fruit without a mate.
The most common ruscus species in cultivation is Ruscus aculeatus, which has a wide range from Western Europe through the Caucuses. A handful of named cultivars of Ruscus aculeatus can be found in the gardens. Below is a photo this month of Ruscus ‘Sparkler’ a self-fruiting form, whose 2′ tall height is mid-way between Ruscus ‘Elizabeth Lawrence’ and Ruscus ‘Wheeler’.
Ruscus hypophyllum is a species, which ranges from Spain to Northern Africa, that’s rarely cultivated in the US. Other than the very tender Ruscus streptophyllus, this has proven to the be the next most tender species. Prior to trying these new forms of Ruscus hypophyllum, which were planted in early 2020, we had only grown a single clone, which had consistently died in our Zone 7b winters. These new plants are seedlings, grown from an Alan Galloway seed collection in Majorca, Spain.
Ruscus hypoglossum, which hails from Italy to Turkey, is a similar sounding species that we were fortunate to study in the wilds of Slovenia a few years ago, where it grew in mountainous open forests.
Ruscus x microglossum (below) is a natural hybrid between Ruscus hypophyllum and Ruscus hypoglossum…quite a tongue-full.
Ruscus colchicus is a species we fell in love with during a trip to Hillier’s Arboretum in 2005. Hailing from NW Turkey to the Western Caucuses, Ruscus colchicus is possibly the most elegant garden species. We are fortunate to have three different clones growing at JLBG, which we hope to one day have enough to share.
Voted least likely to be found in an ex-situ plant collection is Ruscus hyrcanus, a species, whose native range is from the Crimea into Iran. In appearance it somewhat resembles a dwarf, horizontal-growing version of Ruscus aculeatus. We are thrilled to have been able to offer this little-cultivated species in the past through Plant Delights.
We hope you’ll take notice of these great evergreens during your next visit to JLBG.
Another of the mid-winter flowering species of wild ginger is the Chinese Asarum ichangense. Here is a green leaf form of this easy-to-grow wild ginger in late January from the top. If you push aside the leaves, you’ll see the amazing floral show, hidden beneath. Winter hardiness in Zone 6b-8b, and possibly colder.
Here’s a mid-winter shot of our front grotto, showing what that section looks like during the most trying time of year. We try to emphasize to those building new gardens to treat gardens just like rooms of your home. Each should have a floor, ceiling, walls, furniture both large and small, and decorations. In the garden, we also try to emphasize year round interest, which in our area includes a good selection of evergreens. Our Winter Open Nursery and Garden Days coming up in a few weeks is a great time to get ideas and inspiration for your own garden. Below is a “before” picture of the same area.
Below is the same shot when this section was begun in 1988.
The Helleborus x gladorfensis hybrids, known as the “Ice n’ Roses” series have begun with the opening of Helleborus ‘Ice n’ Roses Barolo’. This is the earlies flowering and darkest clone in the series…just a shade darker than H. ‘Ice n’ Roses Red’. These are sterile hybrids derived from crossed of Helleborus niger with Helleborus x hybridus. Winter hardiness is Zone 5a-8b.
Asarum hypogynum ‘Artist’s Palette’ is in full flower here at JLBG in late January. Despite being first published in 1915, this little-known species is very poorly represented in ex-situ plant collections worldwide. Our clone is a division from a wild plant we brought back from our 2008 botanical expedition to Taiwan. The foliage on this species is some of the largest in the entire genus. For us, Asarum hypogynum starts flowering in late summer and continues most of the winter. We are working to eventually be able to share this with other collectors. Hardiness is Zone 7b and warmer.
We love busting horticultural myths, and here’s our latest. Borinda fungosa is another of the wonderful clumping bamboos from China, which, according to bamboo authorities, will not tolerate either our winter temperatures or our summer heat and humidity. Well, darn!
Excuse us for sharing this photo from late January, but here is our 2010 planting of a seed grown plant, and of course, it’s easy to see how poorly it’s growing. That said, we know that it will die to the ground at single digits F, and then re-sprout the following spring. The lesson…don’t believe everything you hear or read.
We truly love loquats…both to grow and consume. I first met Eriobotrya japonica in 1976 on a walk around the NC State campus with the late Dr. JC Raulston. I was amazed to see a mature 30’+ specimen growing against one of the campus buildings. I was determined to grow one of our own, so in the mid 1990s, we planted our first specimen here at JLBG.
Loquats, a Chinese native member of the rose family, makes a lovely small tree with large, evergreen foliage that resembles a corrugated Magnolia grandiflora. Another exceptional feature is the fragrant white flowers that start to open around Christmas. These are followed by delicious orange fruit in early spring, when winter temperatures don’t drop below the mid-teens F. Loquat foliage is also brewed as a tea, in addition to its numerous medicinal benefits. We have always found loquats to be much more winter hardy than most of the literature indicates. Our oldest specimen planted in 1997, has never experienced any winter damage. Hardiness is Zone 7b and warmer.
Asarum minus ‘Cupid’ is one of our heavily silver patterned selections of our native wild ginger. When cold weather arrives, the evergreen leaves take on a lovely purple cast. This is an excellent clonal selection we made in 1994 from a construction site, and one we hope to offer in the future though Plant Delights Nursery.
In full flower now at JLBG is Mahonia x lindsayae ‘Cantab’, a hybrid of Mahonia japonica and the virtually unknown Mahonia siamensis. The intensely sweet fragrance is truly intoxicating…the strongest in the genus Mahonia. Sadly, you’ll rarely find this available for sale, since it’s somewhat gangly form doesn’t curry favor with most nursery growers. Winter hardiness is Zone 7b and warmer.
Camellia japonica ‘Tama no Ura’ has been fabulous this winter, both when the flowers are attached as well as when they just fall to the ground below. This amazing plant was actually discovered in the wilds of China, so no breeding was involved in its creation. It was subsequently introduced to horticulture in 1947 by the Nuccio family of California, who have since worked to create a series of similar flowered selections using these same genetics…all superb.
Here’s an image taken this month of the wonderful Aucuba japonica ‘Limbata’. While most aucubas have yellow leaf specks, this old cultivar, first mentioned in historical literature in 1864, is sadly still quite unknown in gardens. That’s not too surprising, however, due to its slow production time as a commercial nursery crop. For dry shade in Zone 7a-9, this wonderful broadleaf evergreen is hard to beat.
Just out in the garden in early January and wanted to share photos of a few of our favorite evergreen ferns that would rather not be growing in the ground. In our garden, these are all growing within a few feet of each other.
Each of these ferns are epiphytes, which grow attached to a tree, or lithophytes, which grow attached to a rock. None of these ferns actually need soil to grow, since they get their food and water from the atmosphere and accumulated organic debris. Epiphytes, however, don’t get nutrients from their host plant…only physical support.
All epiphytic ferns thrive in hanging baskets, especially the spaghnum-lined type, since this most closely mimics their natural preferences. In our case, we are a bit colder than their native haunts, so for us, we force these ferns to reside in the ground since that gives them a bit more protection during severe winter temperatures. The key for epiphytes to survive in the ground is to have very loose, organic soils and always plant them on a steep slope.
Neolepisorus fortunei ‘Green Ribbons’ is our 2017 introduction of a Chinese native epiphytic fern.
Pyrrosia lingua ‘Hiryu’ is also an epiphytic fern, native to Japan.
Lastly is Polypodium vulgare ‘Ulleung Island’. Instead of being an epiphyte, this evergreen fern is a lithophyte. Lithophytes are classified as either epilithic (growing across the rock surface) or endolithic (growing in cracks or crevices). Since we found this in the wild, growing across the surface of a giant rock, this fern is an epilithic lithophyte…say that three times fast. This is our 1997 collection from an island, far off the coast of South Korea.
We hope you’ll explore these unique ferns in your garden.
We always love it when unexpected garden hookups yield unexpected results, and such was the case recently when, under the cover of darkness, two of our holly ferns took a liking to each other. The result of this conjugal interlude is our first hybrid of Cyrtomium fortunei x Cyrtomium falcatum, that we’ve named Cyrtomium x fortatum Spornication. The habit of the hybrid is intermediate between both parents. Now, we’ve just got to figure out how to get it propagated in order to share.
Helleborus niger ‘Jesko’, aka: Christmas rose, has been looking fabulous in the woodland garden since late December. We find light, open shade results in the best flowering.
Following right behind Helleborus niger in our garden is Helleborus x ballardiae ‘Cinnamon Snow’…a hybrid with Helleborus niger. This is a photo from New Year’s day.
Rohdea japonica ‘Shishi’ is looking lovely in the woodland garden. Rohdea ‘Shishi’ is a dwarf Japanese selection of the evergreen sacred lily with leaves that curl downward creating an unusual bird nest like appearance. Winter hardiness is Zone 6b-8b.
Borinda macclureana is another superb clumping bamboo that has never received the good PR afforded other more popular species. Collected in Tibet at nearly 11,000′ elevation, it really has no business growing in the hot, humid southeastern climate, but that’s why we trial plants. Although Borinda macclureana can reach 25′ in its native haunts, our 15 year old specimen has only reached 8′ tall x 8′ wide.
We recently had someone inquire if we grew tractor seat plant, a common name I had not heard prior. After a brief pause, I figured few plants, other than our 2000 introduction, could possibly fit that name. Sure enough, a quick web search confirmed that Farfugium japoncium var. giganetum ‘Marco’ is indeed their target. While wandering through the garden this weekend, I found one clump still in flower, that somehow avoided damage from several nights at 27 degrees F.
To our knowledge, this giant form of Farfgium japonicum, native Japan’s southernmost Ryukyu Islands, was first brought to the US by plantsman Marco Stufano, who rationed out one plant per year for a NY Rare Plant Auction. When Marco was ready to retire from Wave Hill, he finally shared a piece with us, so we could get it mass propagated, hence we named the clone in his honor. To our knowledge, all tractor seat plants sold in the US came from Marco’s original plant.
This is the best fruit set we’ve ever seen on the Chinese Disporum longistylum ‘Green Giant’. We love this semi-evergreen Solomon’s Seal, that was collected and introduced years earlier by our friend, plant explorer Dan Hinkley. On the West Coast, this reaches 7′ tall, but here in the hot, humid southeast, we’ve never had ours exceed 3′ tall. Nevertheless, we’ll enjoy our great crop of cobalt blue fruit this winter.
One of several rare wild gingers we grow is Asarum lewisii, which has a small native range limited to central NC and adjacent Virginia. In the wild, the evergreen Asarum lewisii is quite unique in only producing a single leaf every few inches to over 1′ apart when growing in leaf duff. In the garden, however, leaves are much more dense as you can see in the photo from the JLBG gardens this week. It’s ashamed it doesn’t sell better when we offer it through Plant Delights.
We love the evergreen holly fern in all it’s species and forms. Cyrtomium falcatum ‘Butterfieldii’ is looking absolutely stupendous in the garden this month. This easy to grow shade lover glistens all winter with its glossy foliage with fancy serrated edges. Hardiness is Zone 7a-8b.
The cast iron plant, Aspidistra tonkinensis ‘Hanoi Honey’ has been looking quite stunning recently during its December flowering period. Unlike many cast iron plant that have reddish cinnamon flowers, this dazzler has large bright white flowers that are impossible to miss. Where it isn’t winter hardy, cast iron plants make fabulous, easy-to-grow house plants.
Bambusa multiplex ‘Alphonse Karr’ is looking so hot this winter with its amazingly striped canes. This clumping bamboo is usually grown as a die-back perennial here in Zone 7b, since it goes to the ground when temperatures drop below 10 degrees F. Because we’ve had three mild winters, we are once again able to enjoy the amazing striping of the canes. I did get a chuckle last year, when I saw Bambusa multiplex show up on an invasive species list for North Carolina. As I explained in my letter to the group, Bambusa multiplex is first and foremost, a clumping species. Secondly, all truly invasive species (which invade functioning natural ecosystems, displacing natives and causing economic harm once population equilibrium has been reached) must be able to spread by seed, and bamboo clones only flower once in 100 years, and then die. It’s these emotionally driven lists, without any basis in facts or real science, that makes so many of the invasive lists a farce, and sadly untrustworthy.
Here’s one of our favorite hollies, looking great in the garden this week. Ilex integra ‘Green Shadow’ is a variegated (creamy-edged leaves) form of the Mochi holly. This amazing columnar holly, that hails from oceanside mountain slopes in Japan, Korea, Southern China, and Taiwan, reaches 20′ tall x 7′ wide, which is the case with our 16 year old specimen. Although Ilex integra ‘Green Shadow’ will grow in both sun and shade, full to half day sun results in the most dense foliage. This is female clone, but we never see more than a dozen berries, so we assume it needs a male nearby to fruit better. For a narrow evergreen screening plant, it’s hard to beat. Hardiness is Zone 6b-9b.
Anyone who has visited JLBG, knows we are huge fans of the Japanese sacred lily, Rohdea japonica. While the variegated forms are certainly showy, we also love the solid green varieties, especially the narrower leaf forms, so here are a few of our favorites. The top is Rohdea japonica ‘Fukuju Kan’, followed by Rohdea ‘Feelin’ Groovy’, and finally Rohdea ‘Line Dance’. All photos were taken in our gardens this week. For us, these amazing evergreen plants remain looking great all winter and the orange-red winter fruit are a bonus. In the garden, they function like evergreen hostas. The first two are what is known as dragon-ridge (crested) varieties. Hardiness is Zone 6b-9b.
We love fall and winter, when Woodwardia orientalis ‘Mama Mia’ starts producing baby ferns on the old foliage. Mama Mia can be propagated from the plantlets, but in our cold winter climate, the babies rarely mature unless taken indoors for the winter. The evergreen foliage of Woodwardia orientalis will show damage at about 10 degrees F and Zone 7b is the northern-most range of its cold hardiness.
Sarcococca saligna is one of our favorite species of sweet box, but sadly one of the most tender. If winter temperatures drop below 10F, it dies to the ground, but has always resprouted. When we have mild winters, it becomes an extraordinary woodland garden specimen as is evidenced by this current photo.
One of our most cherished evergreens in the winter woodland garden is the narrow-leaf form of butchers broom, Ruscus aculeatus ‘Chenault’. Our plant came from the Elizabeth Lawrence Garden, and Elizabeth’s plant originated in France’s Chenault Nursery circa the 1960s. Our 20 year old plants are now 3′ tall x 4′ wide. Although they rarely fruit, they provided a unique texture compared to most other forms of the species.
We don’t have many Siberian plants which thrive in the southeast US, so we get pretty excited when we find one that does. I was introduced to Microbiota decussata by the late JC Raulston, back in the mid 1970s, and actually still have one of my original plants that’s still alive. Many years later, a much improved form came to market under the name Microbiota decussata ‘Prides’.
Microbiota is a monotypic genus of conifer that has a textural appearance somewhere between a Juniper and a Selaginella. In the wild, Microbiota can only be found in one small region of the Sikhote-Alin mountains, which is about 500 miles north of Vladovostok, Russia, where it occurs between 6,500′ and 7,000′ elevation.
Although Microbiota was officially discovered in 1921, and published in 1923, the Russian government, long-known for its secrecy, kept it completely under wraps until the early 1970s.
Unlike most junipers, which need sun to thrive, microbiota prefers shade to only part sun. Consequently, it you like this texture and don’t have full sun, this is the plant for you. For us, it matures at 18″ tall x 6′ wide.
Here is the wonderful Fatsia japonica ‘Variegata’ in our garden on Oct 25. This fabulous shrub is a member of the aralia family, and a first cousin of the off-despised running ivies. Not only do we love Fatsia for its amazing bold texture and evergreen foliage, but we love it because it flowers in fall. The second photo was taken a mere four weeks later, when it had exploded in full bloom.
Fatsia japonica is a superb pollinator plant at a time when so little is in full bloom. Our winter low temperatures so far have been 27 degrees F, which hasn’t affected the flowers. Winter hardiness is Zone 7b and warmer.
Due to having three consecutive mild winters, with no temperatures below 20 degrees F, we’ve actually been able to get a trunk on our Washingtonia filifera palm. Typically not hardy in our climate, our plant was grown from seed collected from a wild population in Arizona that had experienced 10 degrees F. We’ll see what this winter has in store.
Most gardeners in mild winter climates are familiar with Liriope (monkey grass), and Ophiopogon (mondo grass), but almost no one is familiar with the third cousin, reineckea (false lilyturf). Like both better known cousins, reineckea is an evergreen groundcover, but unlike the others, here is our clump of Reineckea ‘Little Giant’ in full flower for Thanksgiving. Depending on your taxonomist, there is between 1-3 species in the genus. We’re certain of three and think there may be more. We have assembled a collection of nearly 30 wild collections and will be working with other researchers to sort out the taxonomy of this group.
We are just loving our hardy hybrid cycads in the garden this time of year, and here are two we photographed this week. The first is Cycas x bifungensis (bifida x taitungensis), and the second is Cycas x panziholuta (panzhihuanensis x revoluta). We have found that hybrids between hardy species are even more winter hardy than the species themselves. Hardiness for both is probably Zone 7b and south.
How could you not love a plant with the name poet’s laurel? Poet’s laurel has a long history in Greek and Roman culture representing praise for a victory or great achievement in the form of a laurel crown. Danae woven-stem wreaths were also bestowed upon revered members of society who, if they then lived off of their past glories, were said to be “resting on their laurels.”
The laurel referred to, is Danae racemosa, a classic pass-along plant in Southeast gardens, although it originally hails from half-way around the world…Iran and into the nearby Caucus Mountains. In the florist trade, where it’s highly prized, it’s often referred to as Italian laurel.
The evergreen Danae racemosa is hardy from Zone 7a and south, and fruits best in very open shade to a couple of hours of morning sun.
One of our favorite fall woodland plants is a member of the Aster family, belonging to the genus farfugium. Farfugiums have long had a bit of an identity crisis, as they were originally named in 1767 by Linnaeus as Tussilago japonicum. In 1768, the same plant was also published as Arnica tussilaginea. Then, in 1784, it was moved to the genus, senecio, and became Senecio japonicus.
Later in 1891, it was renamed again, this time as Senecio tussilagineus. It remained in the genus senecio until 1904, when it moved to the genus Ligularia, and became Ligularia tussilaginea. Here it remained until 1939, when it became Farfugium tussilagineum, but corrected the same year to match Linnaeus’s original epithet, resulting in Farfugium japonicum, which it remains today.
Below is our plant of the typical species, Farfugium japonicum in flower at JLBG this week. Through the decades, we have been collecting an array of other forms. Light open shade or a tiny bit of morning sun and average to slightly moist soils produce the best results.
Farfugium ‘Roundabout Fall’ is our selection of a hybrid with our Taiwanese collection Farfugium japonicum var. formosanum and the typical form. We like the smaller, thick, rounded leaf shape.
Farfugium ‘Jagged Edge’ is another upcoming JLBG/PDN introduction, scheduled for a 2023 release. It forms one of the larger clumps of any farfugium cultivars we’ve grown.
Farfugium ‘Bashi Ogi’ is the only cultivar we know of Farfugium japoncium var. luchuense. This rare variety hails from Japan’s southern Ryuku Islands of Okinawa and Kagoshima. It differs in appearance by being a much smaller plant with leaves which are wider than tall. Here is our plant flowering now here at JLBG.
For 2022, Plant Delights will introduce JLBG’s first selection of Farfugium japonicum var. luchuense, that we’ve named Farfugium ‘Sweet Spot’. It’s a miniature seed selection from the above Farfugium ‘Bashi Ogi’, that only gets a few inches tall, so will make a great house plant, where it isn’t winter hardy.
