I’m more and more impressed with Hosta ‘Miss America’ each year. Not only is this white-centered hosta amazingly vigorous, but it has one of the finest floral shows we’ve ever seen on a hosta. The steel rod-like upright flower stalks on our plant have reached 4′ tall, but as the plant grows larger, they will eventually top 6′ in height. Not wind, rain, or post office vehicle can knock down these super sturdy stalks, and the great show they provide for weeks. Our plant is 100′ from our back porch, and it shows up like a floral beacon even from that distance.
This spring, Plant Delights introduced Zac Hill’s 2013 discovery of a new ruellia which he found in central Alabama. What we theorized might be a natural hybrid turned out to be a brand new species, as we were informed by botanists working on getting the plant published. We hope all native plant enthusiasts purchased this to both enjoy in their garden and for ex-situ (off site) conservation value. These are in full flower during the summer. Hardiness is unknown at this point, but we know it’s fine from Zone 7b – 8b, and most likely much further north.
The genus amorpha is a woody cousin to the better know genus baptisia in the Fabaceae (pea) family. Amorpha was named a genus by Linnaeus (perhaps you’ve heard of him) because the flowers only have a single petal, compared to 5, which is the norm in the rest of the family. Virtually all amorphas have many uses, from dyes to treating an array of medical conditions. There is an amorpha native in every one of the Continental United States…how many do you grow?
Our longstanding favorite member of the genus is the Midwest native Amorpha canescens, which makes a stunning, compact deciduous shrub, adorned in late spring with amazing, pollinator friendly flower spikes.
While we had our back turned, one of our Amorpha canescens got jiggy with a nearby Amorpha fruticosa, and the baby below, discovered by our staff, has now been adopted by us, and named Amorpha x frutescens. We actually might have some of these show up in the spring Plant Delights catalog.
Another amazing Southeast US (NC to FL) native species we like is Amorpha herbacea. Although it is rarely available, we think this has exceptional garden value and will most like show up in the Plant Delights catalog in the coming years.
We’ve grown quite a few stachys (pronounced stay-kiss) through the years, but have been most impressed this spring with our newest acquisition, Stachys cretica. This fascinating dryland perennial has a wide natural range from France to Iran, where it thrives in rocky, dry, Mediterranean-like conditions. Our plants are seed-grown from Greek Plantsman, Eleftherios Dariotis, who will be speaking at our upcoming Southeastern Plant Symposium.
Stachys is one of the largest genera of plants in the sage (Lamiaceae) family, with estimates ranging from 300 to over 400 species. Stachys species are spread worldwide, being found from Europe though Asia, Africa, and into North America.
Shockingly, Stachys cretica seems virtually unknown to most gardeners, despite it puttig on a killer floral show in an unirrigated bed, and being foraged in our garden, by a huge number of bumblebees.
The Greek bellflower, Campanula formanekiana has been superb in the crevice garden this spring. This amazing monocarpic (dies after flowering) species take three years to flower, and when it does, it puts on one heck of show. It’s namesake was Czech botanist, Eduard Formanek (1845-1900). We’re hoping for a good seed set. Hardiness is Zone 7a-9a, at least.
A couple of our favorite native redbud selections looking exceptional after flowering today…Cercis canadensis ‘Flame Thrower’ and ‘Golden Falls’…both from the breeding work of NCSU plant breeder, Dennis Werner.
Ok…raise your hand if you’ve grown Aphyllanthes monspeliensis? This odd, monotypic (only member of the genus) is actually a member of the Asparagus family. Hailing from France south into Northern Africa, Aphyllanthes can be found growing in hot, dry, sandy soils, where it produces an amazing spring show of blue flowers on a 1′ tall clumper. The species name “monspeliensis” is named after Montpellier, France, where it grows naturally. Our plants are thriving in our crevice garden, putting on a superb flower show in mid-April.
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.
Aster oblongifolius ‘Fanny’ (Symphyotrichum oblongifolium) has put on its normal superb show this fall. Keep in mind that this gets quite large. This is a 2 year old plant from a quart pot, which has already reached its mature size of 8′ wide.
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.
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.
JLBG is full of blazing stars this fall…some seen when looking down in the garden and others looking up in the night sky. Here are couple of recent images, starting with a Texas collection of the widespread native Liatris aspera that’s looking great in the garden. Looking up in the early dawn hours is also pretty spectacular.
Late summer/early fall is show season for Eryngium aquaticum var. ravenelii…a superb southeast native plant that’s almost unknown by native plant enthusiasts. In the wild, it grows in seasonally flooded ditches, but in the garden at JLBG, our plants thrive in typical garden soil with an average amount of moisture. Here are our plants flowering now…each filled with an array of pollinators.
Flowering this week at JLBG is the little-known, but marvelous Liriope longipedicellata ‘Grape Fizz’, thanks to the exploits of plantsman Darrell Probst. We find this tightly clumping species much more interesting than the more formal Liriope muscari or the weedy, spreading Liriope spicata, and will tolerate full sun to shade. By the way, pedicles are stalk-like structures connecting one plant part to another….in this case the flower stalk to the flowers, hence the specific epithet longipedicellata (long pedicles).
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.
We’ve got some really superb unyaaw’s blooming now. Actually, if you’re not of the Cajun persuasion, they’re onions…of the genus Allium. The North American native Allium canadense is quite showy in the late spring/early summer garden. The first is a superbly dense flowering selection, Allium ‘White Flag’, made by the late bulb guru, Thad Howard. Allium canadense var. lavendularae is a lovely purple-flowered form. Purple seedlings pop up occasionally in wild populations, but we’ve been able to isolate a particularly nice purple form from light lavender flowering plants that originated in Kansas, shared by plantsman Aaron Floden.
