Looking good in the garden this week is the amazing fern, Dryopteris x australis. This rare fern is a US native…despite the confusing name, hailing from only a few scattered locations from Virginia west to Arkansas. In reality, the name “australis” means from the south. This splendid specimen grows in both sun and shade, and tolerates both wet and dry soils. Hardiness is Zone 5a-9b.
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.
Iris ‘Gerald Darby’ is one of those iris that doesn’t even need to flower to be garden worthy. Here it is in our garden this week, emerging with its’ purple leggings. This gem is a North American native hybrid of Iris versicolor and Iris virginica, known as Iris x robusta. This introduction of Iris breeder Gerald Darby was actually named for him after his death by another iris breeder R.H. Coe of England. Iris x robusta ‘Gerald Darby’ is equally at home growing in standing water as it is in typical garden soil. Hardiness is Zone 4a-9b.
Ever since I was a small kid, I’ve observed Zephyranthes atamasco (atamasco lily) in the wild, where they grow in swampy wooded lowlands. Atamasco lily is also one of many great nomenclatural muddles with regard to it’s correct spelling. When it was first named by Linneaus, back in 1753, it was assigned to genus amaryllis, so the specific epithet was spelled “atamasca”.
In his later work, Linneaus changed the spelling to “atamasco”, which corresponded to the Native American name for the bulb. It remained spelled with an “o” even after it was moved into the genus Zephyranthes in 1821. The problem is that, according to International Nomenclatural rules, the original spelling must take precedent. So, Zephyranthes atamasca is correct. Except…there is an exemption for name conservation, when correcting the name will cause confusion or economic harm. There is currently a well-supported move underfoot to conserve the long-used spelling “atamasco”. And you thought nomenclature was boring!
I’ve long marveled at the diversity within the species, and as an adult have been fortunate to be able to collect offset bulbs from some of the special forms I’ve found.
The top image is a very compact form that we’ve named Zephyranthes ”Milk Goblet’. Below that is one of our larger flowered forms from Alabama that we named Zephyranthes ‘Hugo’. Hugo has 5″ wide flowers in a species where 2.5-3″ wide is typical. Both of these are in full flower now at JLBG.
Looking particularly good this week is one of the Southeast US (NC to Texas) native water orchids, Habenaria repens. This gem flowers through most of the growing season, and hasn’t slowed down as we enter November. Water spider orchid can grow both as a marginal or as a true aquatic. Our plant is growing in one of our crevice garden seeps. We’re working to get this really cool native propagated and available in the future.
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…
Don’t let the name fool you, Hymenocallis caribaea ‘Tropical Giant’, as this North American native spider lily (Northern Mexico) has been hardy in our garden (zone 7b) without any protection since 2000. It’s flowering season has begun here at JLBG. Unlike some hymenocallis which require moist soils, this one will grow darn near anywhere. The new flowers open each evening, releasing a sweet fragrance that attracts night-pollinating moths.
Flowering now at JLBG is one of our cute Southeastern natives known as Bog Buttons (Lachnocaulon anceps). The entire family, Eriocaulaceae, has a similar stature with small grass-like foliage, topped by these long antennae-looking structures. In the wild, these can be found in low, often flooded ditches, but they are easily grown in constructed bog gardens. I expect if these were from a more exotic location, more people would grow them. We think they are pretty darn cute.
While exploring the garden yesterday, I was admiring the cardinal flowers, Lobelia cardinalis, in the bog garden. Most of the flowers were red, there were a couple that were more magenta and a few blooming white .
And then several feet away there was one that was a bicolor. Not sure who was the baby-daddy and who was the baby-momma, but we like the results! What happens in the bog garden stays in the bog garden.
