Umbrella Plant, Indian Rhubarb, Peltiphyllum peltatum
One of the few western United States natives comfortable in the east, the Umbrella Plant is best suited for wet places such as stream banks and bog gardens. In spring, its big flowers attract attention. Later on the show centers on its 1- to 2-foot-long leaves, which are shaped like shields. Keep soil moist.
Best in areas with damp ground, because it needs heavy watering. Stalks up to 6 feet tall and leaf blades up to 2 feet across.
