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.
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.
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.
Flowering at JLBG this month is one of our favorite small trees, Cyrilla racemiflora…aka: swamp titi. Cyrilla racemiflora was a favorite tree of the late J.C. Raulston, who was constantly extolling its virtues to anyone who would listen. Swamp titi has a native range from coastal Delaware south and west to East Texas. The flowers, which have just recently started here are a favorite of the native bumblebees. Mature size is usually 10-12′ in height, and the contorted nature of the trunks usually produce a plant that is slightly wider than it is tall. Despite its southern origins in swamps, Cyrilla is well adapted to regular garden soils as far north as Zone 5. As far as the common name, we have no idea where “titi” originated. We’ve read theories that it may have been a corruption of TyTy, Georgia, or have some relation to Florida’s Titi Creek, but those are all unconfirmed.
We’ve got a different take on going tubing. For us, tubing is something we do, starting in mid-June each summer, when we sit and enjoy our patch of Sinningia tubiflora. This amazing South American (Argentina, Uruguay, and Paraguay) gesneriad (African violet cousin) forms masses of underground potato-like tubers, which produce these amazing stalks of sweetly fragrant flowers for months each summer. These are reportedly pollinated by sphinx months. Sinningia tubiflora is insanely drought resistant and so easy to grow if given enough sun. Since it forms a large mass, don’t plant it near smaller, less-aggressive neighbors.
Turn your garden into a pollinator’s paradise with a progression of blooms throughout the seasons.
