Buddleia is a genus of about 100 species of mainly shrubs but also some trees and climbers. They are native to Asia, Africa and North and South America. Commonly called butterfly bush they are very attractive to butterflies and other pollinators.Genus name honors the Reverend Adam Buddle (1660-1715), English botanist and vicar of Farmbridge in Essex. The genus name is frequently listed today as Buddleia. However, Linnaeus named the genus Buddleja(pronounced with a silent “j”) which is still considered to be the proper spelling (first name survives) according to the International Code of Botanical Nomenclature.Common name refers to its attraction to butterflies.‘Bicolor’ is a hybrid cultivar that was selected by Michael Dirr from open pollinated seedlings of B.x weyeriana ‘Honeycomb’ (usually a sterile hybrid) in a planting at test gardens at the University of Georgia. As the cultivar name suggests, ‘Bicolor’ is noted for producing both yellow and raspberry colored flowers within the same flower panicle. Panicles (to 5-6” long) bloom from late spring through summer, often continuing into fall. Flowers are fragrant, and very attractive to butterflies. Lance-shaped dark green leaves (to 8” long). When hard-pruned annually, butterfly bush will typically grow to 6-8’ tall per season with an upright-arching to spreading habit.
