100 MIXED COLORS BUTTERFLY BUSH Buddleia Davidii Flower Shrub Seeds by Seedville BLOOM TIME: Mid Spring - All Summer HARDINESS ZONE: 4 - 9 PLANT HEIGHT: 72 - 96" . . . PLANT SPACING: 48 - 60" LIGHT REQUIREMENTS: Sun . . . SOIL / WATER: Average Pink, Purple, White, and Bluish Mix. The tiny fragrant flowers of the Butterfly Bush cluster together in huge cone shaped bunches for a lovely display. They make an excellent cut flower and attract all of the good stuff - bees, butterflies including MONARCHS, and birds including HUMMINGBIRDS! I think they are very appropriately named because I can tell you there is no other flower in my yard I see more butterflies on.
