Davidia involucrata var. vilmoriniana - The Handkerchief Tree is most spectacular in flower. Two huge, white dangling bracts surround the actual flower. The upper bract is 3 to 4 inches high by 2 inches wide; the lower is a stupendous 7 inches long by about 4 inches wide. Each flower is attached to a 3-inch peduncle. The flowering event is late spring or early summer. Leaves are rounded and serrated often emerging with a purple-bronze flush. They are reminiscent of Linden. Site in sun to part shade in fertile ground. Full to half sun. Protect at the northern end of its range for the first 3 winters at least; though not impossible - especially in a sheltered location - Davidia involucrata can be tricky to establish in USDA zone 5. It will require planning and attention to make it happen. This is another laudable E.H. Wilson introduction. And though we indicate 30 to 50 feet in height it may in the absolute best condition rise to a staggering 60+ feet. Well-rooted small tree from cutting.
