Sweet little Bunchkin

Looking great in the gardens this week is our 2021 introduction of Baptisia ‘Blue Bunchkin’ (available again in 2023). Baptisias are North American native perennials and are equally at home in a bone dry site or as a marginal aquatic…as long as they get at least 4-6 hours of sun daily. Hardiness in Zone 4a-9b.

Take a peek inside our baptisia breeding and trial beds with Tony.

A Pitcher of Flowers

Here is a small sampling of the amazing array of flowers that are in the garden currently (late April/early May) on our pitcher plants. The genus Sarracenia is native to North America and hails from Canada south to Florida, where they are found in seasonally damp bogs. In the garden or in containers, they are incredibly easy to grow as long as they have moist toes (roots), and dry ankles (base where the crown meets the roots). Winter hardiness varies based on the species, but most are hardy from zone 5a to 9b.

The Crevice is “Woke”

The crevice garden has “woke” for spring, with early flowering plants in full gear. Here’s a shot of one small section, featuring Delospema dyeri and Iberis simplex (taurica). We hope you can visit in person for the second weekend of our spring open house, May 6 – 8, 2022.

Do you have hairy puccoons?

I fell in love with puccoons several decades ago, when I first saw them growing on the Michigan dunes as I hiked around the shoreline. I was immediately smitten with this native member of the Borage (pulmonaria) family. There are 21 different species of Lithospermum (puccoon) in the US, where some go by the common name, stoneseeds.

It would take me five transplant attempts over the next three decades before we were able to successfully get one established in the garden. The photo below is our collection of Lithospermum caroliniense (hairy puccoon) from East Texas, flowering now in it’s new home adjacent to our crevice garden. This species is partial to acidic, sandy soils, so our next task is to figure out what other conditions it will tolerate and then to get it propagated, so we can share.

A Characias Cracker

For years, we struggled to grow the Mediterranean/Balkan native spurge, Euphorbia characias…until we discovered its secrets. First, it isn’t a long lived plant to begin with…in most cases 3-5 years is it, so you’ll need to plant it where it’s likely to reseed. That would be well-drained slopes that are either mulched or covered with gravel.

Secondly, after it flowers in spring with its stunning show of yellow flowers, remove most of the flower stalks as soon as flowering has finished, except those needed to produce new seedlings (the flowers are also great to use in floral arrangements). If not, the seed stalks use up energy causing the plant to decline much faster. We’ve now allowed this to seed throughout the slopes in front of our house, and here is the result…a smattering of 3′ tall x 3′ wide clumps, photo taken mid-winter.

Although this section of the garden, planted in compost-amended sandy loam is irrigated, we typically don’t recommend irrigation for this spurge without excellent drainage. You’ll also read on-line that Euphorbia characias doesn’t like hot, humid summers…another example of fake gardening news that just keeps getting repeated without any concern for the facts.

We’ve also found Euphorbia characias to grow well in part sun under large trees, which keeps the soil dry. The plants will never be as dense as they are in full sun, but they survive and flowers. There is really not anything else that gives you this evergreen blue color and form in the winter garden.

Kaizuka! Bless you.

I first met Juniperus chinensis ‘Kaizuka’ on a mid 1970s student field trip to Florida with the late JC Raulston. As our caravan of University vans crossed from Georgia into Florida, these junipers suddenly appeared everywhere. Although, I was unfamiliar with this architecturally fascinating specimen, I was in love….despite it being common as the proverbial dirt in Florida landscapes. Everywhere from gas stations to the poorest home seemed to have at least one. Most locals know Juniperus ‘Kaizuka’ as either Juniperus ‘Torulosa’ or Hollywood Juniper…a common name it gained due to its ubiquitous presence around Los Angeles. It turns out that Juniperus ‘Kaizuka’ was an introduction from Japan’s Yokohama Nursery prior to 1920. Our oldest plants at JLBG are now 33 years old, and now measure 24′ tall x 16′ wide. The one pictured below is a new 5 year old planting in a new section of the garden. Forty-five years later and still in love!

Red China

The dwarf groundcover Sedum tetractinum ‘Little China’ is superb throughout the growing season, but we particularly love when cold weather arrives and the olive green foliage turns to bright red in the sun…what a superb winter show. Hardiness is Zone 4a-8b.

Beyond Flowers

We love the appearance of plants like agapanthus in the fall, long past the season when the showy blue flowers graced the top of each now browning stalk. In fall, it’s more like looking out on a mass of punk rock hairdos. These garden features are so much more interesting than flat beds of mulch, created far too early by garden neat freaks. This is the cultivar Agapanthus ‘Prolific Blue’ which puts on a superb fall/winter show.

Find you a Redneck Girl

The splendid, giant-growing Salvia madrensis ‘Redneck Girl’ is a JLBG introduction and has been at peak the last few weeks. This is so superb for climates where you can avoid an early fall frost.

Jammin’ Jame

Salvia regla ‘Jame’ (pronounced Haam-hey) is looking so wonderful this time of year. This amazing North American native (US/Mexico) was originally shared back in 2000, by the late Salvia guru, Rich Dufresne. It has adorned our gardens every year since with these amazing fall shows. Hardiness is Zone 7b and warmer.

Have a Fall Flowering Show

There are few plants that put on a better fall show than the amazing Eupatorium havanense, now known as Ageratina havanensis. This oustanding Texas native is flowering now, having burst into flower in early November, providing nectar for a wide variety of insects, and great floristic enjoyment for a wide variety of gardeners. Plant Delights offered this for a number of years, but sadly, few people could be enticed to purchase one. Hardiness is Zone 7b and warmer.

Eupatorium havanense

Captain Kirk’s Crinum

About the same time that America’s Captain Kirk blasted off into space recently, we were enjoying his namesake here in the gardens at JLBG. Crinum kirkii is a fantastic dwarf crinum lily to only 18″ tall, that is sadly almost never seen in commerce. Full disclosure…Crinum kirkii was actually named for botanist Sir John Kirk, who found and sent this previously undescribed species from his outpost in Zanzibar to Kew Gardens in 1879.

Crinum kirkii has thrived for us here in Zone 7b since 2012. Our plants of this African species are from Tanzania. Perhaps one day, we can produce enough of these to share.

Drinks anyone?

Couldn’t resist this photo of a couple of carpenter bees looking for a drink after a hard day of work, and happened on this enticing stray pitcher full of water. Oh, if they only knew…

Georgia Savory

Flowering this week is the amazing Southeast native subshrub, Clinopodium georgianum. The leaves have a wonderful fragrance of strong peppermint, and the flower show isn’t bad either. This is Zac/Jeremy’s collection from Henry County, Alabama.

A carpenter bee working nearby stopped in for a floral snack.

Aster ‘Hillandschmidt’

Symphyotrichum pilosum

Here is a future introduction for Plant Delights, a 2018 Wilkes County, Georgia collection of a dwarf, compact form of our native frost aster, Aster pilosus (Symphyotrichum pilosum), collected by our research staff, Zac Hill and Jeremy Schmidt. It’s looking rather impressive in the trial garden this week, 30″ tall x 5′ wide.

The Purple Passion Mystery

Last year, we saw a listing for a new Mangave, M. ‘Purple Passion’ on the availability of a West Coast liner producer, so we ordered some to try. It was immediately evident when we unpacked the shipment, that the plants didn’t look anything like a mangave, nor did what we received match the image that the supplier had on their website.

As we dug deeper, we found that the supplier had misappropriated a mangave image from another wholesaler and was using it for the plant we purchased, desptie the two looking nothing alike. Once the image issue was remedied, we set out trying to track down the origin of this strange plant, which looked more like a steamrolled eucomis than a mangave.

The supplier sent us to their supposed source, who had never heard of the plant in question. For six months, we have chased down one lead after another, contacting all of the well-known plant breeders of these type of plants on the West Coast. All dead ends.

Examining the plant in our garden this summer, it occurred to us that the unusual leaf netting must have come from a beschorneria. Comparing the foliage netting of ‘Purple Passion’ to beschornerias in our garden yielded a perfect match, except for the leaf color. The only plant which could have been crossed with a beschorneria to give such leaf color is a manfreda. Hence, our conclusion that our plant is in fact a new bi-generic hybrid, x Beschfreda ‘Purple Passion’ (beschorneria x manfreda).

Since we don’t know which species of beschorneria was used, we are uncertain about potential winter hardiness, but with plants in the ground now, all we need to do is wait for cold weather. Below is a photo of the plant in the garden this week. If you happen to know more of the backstory of this fascinating plant, please let us know.

Exploding Little Volcano

Lespedeza ‘Little Volcano’ puts on quite a show each fall. Here it is in the garden this fall in full bloom. This amazing dieback perennial reaches an amazing 7′ tall x 15′ wide in good soils and full sun. Our friend Ted Stephens is responsible for bringing this gem from Japan to US gardeners.

Sunrise over Maui

Here’s a recent image of the amazing Colocasia esculenta ‘Maui Sunrise’, still looking great in late October! Moist, rich soils and full sun are the key for your plants to look this spectacular! Winter hardiness is Zone 7b and warmer.

Sex for the Centuries

Since we are limited in the number of hardy century plant species, our only option for more agave diversity in the garden is to create it by crossing existing hardy species together. Here are a few of our recent successes.

Agave x amourifolia is a Plant Delights/JLBG creation from a cross we made in 2016 that combined the genes of three century plants, Agave ovatifolia, Agave lophantha, and Agave x pseudoferox ‘Logan Calhoun’. Our size estimates were that the offspring would mature at 3′ tall x 5′ wide. Here is one of our garden specimens photographed this week, which has already reached 2′ tall x 3′ wide.

Agave x amourifolia

Below is Agave x ovox, a 2017 cross of the two giants, Agave ovatifolia and Agave x pseudoferox ‘Bellville’. We expect this to get huge…perhaps 5′ tall x 10′ wide.

Agave x ovox ‘Large Ox’

Below is Agave x protifolia is a 2016 Mike Papay cross of Agave x protamericana x Agave ovatifolia. We also expect this to get quite massive.

Agave x protifolia

Below is Agave x ovatispina ‘Blue Arrows’, a 2016 Mike Papay cross of Agave ovatifolia x Agave flexispina. We would have expected this to be a mature size, but it’s achieved this in only 5 years, so we think we’re seeing some serious hybrid vigor.

Agave x ovatispina ‘Blue Arrows’

Below is Agave x ocareginae, our 2016 cross of Agave ovatifolia x Agave victoriae-reginae. Most likely, this elegant small grower will never offset.

Agave x ocareginae

Below is Agave x schuphantha, a 2015 Mike Papay cross involving three century plant species, Agave schidigera, Agave lophantha, and Agave lechuguilla. It’s formed a beautiful, symmentrical rosette, which should be getting close to mature size.

Agave x schuphantha ‘Wheel of Fortune’

Dalea…not Dahlia

Our favorite fall-flowering legume is looking fabulous now. While most daleas (baptisia cousins) flower in spring and summer, only one that we’ve grown waits until fall to produce its amazing floral show. Dalea bicolor var. argyraea is an easy-to-grow species, found in the dry alkaline sandy soils of Texas and New Mexico. Here at JLBG, it has thrived everywhere it’s been planted…all dry, un-irrigated beds. Native pollinators love it also.

The Surprises Continue

The parade of Lycoris (surprise lilies) continue into their third consecutive month as we move through September. The key for a succession of flowers is having a large number of cultivars. So far at JLBG, we have flowered 300 different cultivars this summer. Here are a few recent ones. The varieties which form fall foliage are winter hardy in Zone 7a/b and south. Those whose foliage emerges in late winter/early spring are winter hardy in Zones 4/5.

Lycoris x rosea ‘Berry Awesome’
Lycoris x rosea ‘Caldwell’s Red’
Lycoris x rosea ‘Kariwatashi’
Lycoris x rosensis ‘Colorama’
Lycoris x rosensis ‘Three Towers Mirroring the Moon’
Lycoris x sprengensis ‘Lemon Cheesecake’
Lycoris x straminea ‘August Lemon’
Lycoris x straminea ‘Caldwell’s Original’
Lycoris x straminea ‘Red Hot Lover’
Lycoris x straminea ‘Ring of Gold’

Late Summer Rains

We are fascinated with the wonderful genus zephyranthes (rain lilies). Zephyranthes are unobtrusive, summer-flowering bulbs that can fit in any garden, with a flower color ranging from yellow to white to pink. The great thing about zephyranthes is the lack of large foliage that often accompanies many other spring-flowering bulbs, so site them in the front of the border, or in a rock garden to be best appreciated.

Zephyranthes are one of our specialty collections at Juniper Level Botanic Garden, with 25 species and 257 unique clones. Here are a few of the zephyranthes blooming this morning in our alpine berm. You can view our entire zephyranthes photo gallery here.

Mexican combo

Just caught this image of two North American (Northern Mexico) natives snuggled up closely together in the garden. At top is one of the spider lilies, Hymenocallis acutifolia, and wrapped around its ankles is Tradescantia pallida. We truly love Tradescantia pallida as a great combination-enhancing perennial that’s completely winter hardy here in Zone 7b.

Old Fashioned, but not out of Fashion

Hemerocallis ‘Autumn Daffodil’ was introduced in 1949, but remains one of the most incredible daylilies we grow here at JLBG. The 3′ tall, branched, sturdy, upright stems are topped with an abundance of amazing highly fragrant yellow flowers starting in July.

Cooking up a Joe-Pye

We wanted to create a buffet for local butterflies by our patio, and a mass planting of Eupatorium purpureum ‘Little Red’ did just the trick. Not bad for a highway ditch native.

Flaming Torch of Summer

The 7′ tall, and very floriferous Hedychium ‘Flaming Torch’ is looking quite stunning today in the garden. Although they are commonly called ginger lily, they are not a true lily (genus Lilium) or a true ginger plant (genus Zingiber). Hedychiums are prized for their summer and early fall floral shows atop bold-foliaged stalks. The inflorescences are quite exotic looking, resembling clusters of orchids. Slightly moist, rich garden soils and at least 1/2 day sun are best for these hardy tropical looking plants.

Cortaderia ‘Blue Bayou’

This amazing selection of pampas grass is looking particularly stunning at JLBG this summer. This plant has had quite a few false starts in commerce, but hopefully it’s getting a bit closer to being commercially available. We love its compact nature, although it does reach 7′ in height and 10′ wide.

Hark…it’s Arp

Our 4.5 year old clump of Rosmarinus ‘Arp’ has become ridiculously large, as rosemary does. When we moved to our new home, Anita requested one near the kitchen door, which was a no-brainer since I am in love with both her and her rosemary chicken. Rosmarius ‘Arp’ has been one of the most winter hardy of all rosemary cultivars we’ve trialed.

Purple and Gold

If you visit JLBG, it’s hard to miss that we like combinations of purple and gold. Here is a favorite summer combo, planted across from the crevice garden, where we use Rudbeckia speciosa as a foot warmer for Calycanthus ‘Burgundy Spice’…a fun combo using two North American natives.

Plundering Pipes

The Pipevine Swallowtail butterfly caterpillars are munching away on any aristolochia (pipevine) in sight. This week, their favorite in the garden is the stunning Aristolochia fimbriata. Nature has created a wonderful balance where the catepillars each just enough to survive and grow, but not enough to damage the plant, which will quickly re-flush.

Mongolian Heads Up

After a long spring/early summer flowering season, we’re now enjoying the seed head of Clematis hexapetala ‘Mongolian Snowflakes’. Here it is growing in our fully sun, gravelly crevice garden.

Mo Crinum

It’s been a great month for crinum lilies in the garden, so here are a few of our more recent images. Crinums are native in the wild to Africa, North America, South America, Australia, and Southeast Asia. Some are winter hardy to Zone 7, while others are completely happy in Zone 6.

Crinum ‘Antares’
Crinum ‘Peppermint Candy II’
Crinum ‘Bradley’
Crinum ‘River Forks’
Crinum ‘School Bells’
Crinum ‘Sunbonnet’
Crinum ‘So Sweet’
Crinum x baconii ‘Maureen Spinks’

Artful Artemisia

We’ve long prized artemisias in the garden, many for their wonderful silver foliage and amazing texture. We’ve always had a love/hate relationship with the North American native Artemisia ludoviciana. This widespread native (or naturalized species) occurs in every US state between Canada and Mexico, and is divided into eight subspecies. Below is our specimen of a superb collection by Patrick McMillan from Gillespie County, Texas that we call Artemisia ‘Fredericksburg’. We find this a much better plant than the commonly sold Artemisia ‘Valerie Finnis’ and ‘Silver King’, both of which have coarser foliage and spread too fast for our taste. All forms of Artemisia ludoviciana spread to some extent, so be sure to locate it in a sunny location where it can romp.

Orange and Purple together again

Here’s a recent combo at JLBG with Eucomis comosa ‘Sparkling Burgundy’ (our first plant introduction), paired with Hemerocallis ‘Prize Picotee Splendor’ (introduced by our friend Roy Klehm), and backed with Lagerostroemia faurei ‘Townhouse’, an introduction from our mentor, the late J.C. Raulston. For us, it’s about the plants and the people!

Baptisias: Great American Natives!

Baptisias, commonly known as false indigo, are North American native members of the pea family and quite drought tolerant once established. They provide amazing architectural form in a sunny garden or perennial border, and are deer-resistant and a butterfly magnet (See the top 25 flowers that attract butterflies here.).

image of Baptisia 'Blueberry Sundae'

Not only do baptisia come in blue, which many people are familiar with in the most common species, B. australis, but they are also available in a wide array of colors such as white, yellow, purple, and pink, and new breeding efforts are producing bicolor flowers such as those of Lunar Eclipse.

Baptisias have long been one of our favorite groups of sun perennials here at PDN. Through our trials of new varieties introduced  to the market, as well as our own breeding program, we continue to select for improved structure and habit as well as flower color. In 2017, we have introduced 2 new varieties in our Tower Series, Yellow Towers and Ivory Towers. These join our previous introduction, Blue Towers, all having a vigorous upright habit to 4.5-5′, terminating in 18-20″ spikes of flowers, true show-stoppers in the garden.

Baptisia ‘Yellow Towers’

Due to high demand, we quickly sold out of finished stock of Ivory Towers, but don’t fret, we have another crop coming along and they should be ready just in time for our Spring Open Nursery & Garden Days April 28-30 and May 5-7. And be sure to join us on Sunday May 7 at 2pm for our Gardening Unplugged garden chat series, where Tony will be talking about baptisias. You can also read Tony’s more in depth article about baptisias, here.
