|Small tree with 3" rounded green to rich purple, almost black foliage. The name Smoke Tree comes from the lavender to purple plume-like panicles that form in summer, producing "poofs of smoke." Airy clouds of purplish red "smoke" in summer lend an exotic air. Unusual accent or specimen. 'Velvet Cloak' has dark purple leaves through most of the summer and changes to reddish purple in the fall.
