Havana snakeroot or mistflower is a rounded shrub, 2-6 ft. tall, with many much-branched stems arising from the base. Leaf blades triangular to roughly ovate or narrower, up to 3 inches long, with 3 main veins; margins wavy to coarsely toothed, tip pointed, and the base broadly tapered to almost perpendicular. Opposite leaves hang from fairly long leaf stalks. Prolific, long-lasting, fragrant, pinkish-white flowers occur in fuzzy, terminal, ageratum-like clusters. Fruit 1/5 inch long, with a crown of bristles on one end.Blooms best and appears bushier if severely cut back each winter. Drought tolerant. Adapt to most well-drained soils. May be transplanted year-round if cut back by one third.
