We’ve written before about plants that get much larger than we are told in the catalog descriptions. Well, our latest example is Buddleia ‘Sleeping Beauty’, a hybrid of Buddleia lindleyana and Buddleia davidii. In two short years in the garden, it became a monster, reaching a 7′ tall x 12′ wide with no sign of slowing down. It was quite lovely and floriferous, but has now become a welcome member of our compost pile…sigh
We don’t know how many of you have noticed this in the JLBG garden during open house, but this special gem is from a Chinese spore collection by JC Raulston Arboretum director, Mark Weathington. Now that it’s large enough, we have sown spores so we can work with JCRA to introduce this gem to the public.
Our plants of Hibiscus syriacus ‘Capra’ are worthy of a photo share this week. This is the best of the variegated leaf rose of sharon’s we’ve trialed, and so far, it been sterile, which is a requirement for any rose of sharon to remain in our garden.
Hmmm… We love sarracenias…such great garden entertainment and without going on-line!
Late summer and fall are a great time to enjoy the plumes of our US native ornamental grass, Panicum virgatum. Here are two photos from the garden this week. The first is one of my favorites, the giant Panicum ‘Cloud 9’…an introduction from Maryland’s defunct Bluemount Nursery. Below this is a new dwarf, blue-foliage introduction for 2022, from Walters Gardens, Panicum ‘Niagara Falls’. It has proven exceptional in our trials and will appear in the January Plant Delights Nursery catalog.
We admit to a long-standing case of buckwheat envy. Every visit to the worlds great rock gardens, such as the Denver Botanic Garden, leave us lusting to grow the rock garden genus, eriogonum. We’ve killed many members of the genus, since they truly hate our humid and wet summers. Even our crevice garden was no help in keeping these alive, even including our reportedly easy-to-grow Appalachian native, Eriogonum allenii. After almost giving up several times, we can finally declare success with the Texas native Eriogonum longifolium, from our East Texas botanizing expedition. Here’s our clump in full flower, and quite happy in one of the rock garden sections. Granted, it’s not as stunning as some of the species that thrive in Denver, but hey, we can now check that genus off the list.
Early fall is peak ginger lily season, and Hedychium ‘Anne Bishop’ is looking particularly stunning this week. This amazing cultivar always ranks near the very top of our favorites list.
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.
We were harvesting our abundant fig crop last week, and were astounded by the number of green June Beetles also enjoying the ripe figs. This indulging makes the beetles into a sweet and tasty snack for the likes of crows, grackles, blue jays, and mockingbirds.
After gorging themselves through the summer, the beetles burrow 6-8″ down into the soil where they lay their eggs, which hatch in a couple of weeks and then overwinter as grubs, which feed on compost during the winter months. While living as larvae, the grubs are food for many underground mammals as well as above ground foragers like possums, racoons, and skunks.
Although green June Beetles are voracious feeders of over ripe fruit, that probably isn’t fruit you were going to eat any way, so they really aren’t damaging to the garden. Green June Beetles are much larger and less impactful than the dreaded Japanese beetles.
We actually enjoy these fascinating insects and don’t find any need to try and eradicate them. Since they don’t bite or sting, they are great for kids and adults looking for unusual sensory experiences to handle. Holding a green June Beetle in your hand is the best way to get a real buzz, and still be able to drive safely afterwards. The only downside is that they may poop on your hand, but that also is a new experience for most folks.
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.
