Allium ‘Ostara’ is a new bulbous ornamental onion from a cross of the lovely, but difficult to grow (in the southeast US) Allium karataviense and Allium atropurpureum. We’re growing this in our crevice garden, which is working well…so far. We’re hoping the genes from Allium atropurpureum will make this more growable.
We first met the little-known Baptisia nuttalliana back in the late 1990s on a botanizing trip to the gulf coast, and found it fascinating. Unlike most baptisia species, it doesn’t produce terminal spike, opting instead for axillary flowers. It’s namesake is English botanist Thomas Nuttall (1786 – 1859), who discovered it back in the day. Most forms are a bit homely, compared to the modern hybrids, but this beanbag-shaped, dense plant is one we’ve selected for future clonal propagation under the name Baptisia ‘Nuttball’.
We find aucubas an invaluable evergreen shrub for dry shade, and one of our favorites is looking rather nice this week. Aucuba japonica ‘Ogon-no-tsuki’ is also one of the slowest growers due to the large amount of gold in the leaf center. It is our hope to perhaps finally have enough to share in the next couple of years.
Alright, we’re not bending to the equal time fungus lobby, but here’s a really cool lichen we photographed during a recent botanizing trip in East Texas. Wouldn’t it be cool if you could just pick these up and transplant them..
The rare Dryopteris x australis is looking superb in the garden this week. This Southeast native, naturally-occurring hybrid will grow in sun or shade and in wet or average soils. Despite its deep southern roots, it’s fine outdoors in Zone 5a. 4′ tall..pretty amazing!
Our baptisia introductions are looking absolutely fabulous this week. Here are a few in case you missed the first weekend of our open house. Baptisia ‘Aspriing’ (top) with its long spikes of lavender blue flowers, followed by the incredibly dense flowering Baptisia ‘Blonde Bombshell’. Next is our Baptisia ‘Cherry Pie’, which brings a new color to the genus, and ending with Baptisia minor ‘Blue Bonnet’ with it’s enormous blue flowers. Baptisia are a North American genus of long-lived perennials that can grow equally as well with cactus or as a marginal aquatic…as long as they have full sun.
Earlier we posted photos of wild collected Amsonia tabernaemontana, so here is a closely related species that’s been hopelessly mixed Amsonia tabernaemontana, thanks to mothball-sniffing herbarium botanists. Amsonia glaberrima is a gulf coast species that’s actually quite different…smooth leaves for a start, and different habit and flowering time. Here is our garden selection grown from a seed collection in east Texas. This is a truly exceptional plant, so I expect we’ll get our propagation staff to tackle this after flowering.
We’re always looking for more “green mulch” plants, which cover the ground, reducing weed pressure, while not choking out desirable plants. One such plant we feel should be more widely grown is Erigeron pulchellus. This amazing perennial is native to every state east of the Mississippi River. So, why isn’t it grown in every garden? Inquiring minds want to know. The rosettes lay flat on the ground, but are topped right now with short 8″ spikes of blush pink daisies. Our photo from the garden this week is the clone Erigeron pulchellus ‘Lynnhaven Carpet’. Erigeron pulchellus is easy to grow in average soils in light shade to part sun.
Blooming now in the crevice garden is one of our favorite edimentals. If you haven’t heard this word before, it’s the new combo term for edible ornamentals. Crambe maritima, known as sea kale, is a plant we first grew for its fragrant flowers, only to find it incredibly tasty, both fresh and cooked. We are constantly grabbing a leaf for a garden snack. Best of all, Crambe maritima is a perennial that doesn’t need to replanted yearly. We can’t imagine why every lover of kale doesn’t grow this. Dry full baking sun is all that’s required.
Few flowering plants are older than members of the genus chloranthus, which first originated between 22 and 150 million years ago, during a time that flowering plants were just evolving, and long before nurseries or garden centers came into existance. Chloranthus aren’t just interesting botanically, they also are unique textural plants for the spring woodland garden, where they are amazingly easy to grow. Here are two of our favorites in bloom this week…Chloranthus japonicus and Chloranthus sessiliflorus ‘Get Shorty’.
