Bignonia violacea is an older, but still commonly used name for Clytostoma callistegioides which has been through a few different reclassifications over the last several years.  As the genome was sequenced the horticultural community learned more about exactly how it is related to other plants, and some name changes have occurred.  If you’re looking for a tropical flavor, but can’t exactly baby your garden, Lavender Trumpet Vine is a remarkably good choice.  This Bignonia is not picky about soils or irrigation once it’s gotten itself established, and will quickly fill out to ten or more feet in height, climbing wherever the tendrils can find purchase.  Plant Bignonia where it will get full sun, if you want to get the best show of flowers.  Despite being a quick grower, Bignonia violacea is not especially aggressive, and does not seem prone to invasive behavior.  Plant Lavender Trumpet Vine where the thick evergreen foliage and generous show of hummingbird-attracting flowers is desired.
