Doronicum orientale

Doronicum orientale (Leopard's Bane) is an ornamental plant in the Asteraceae family. It is a hardy (to zone 3) perennial, unusual for blooming from early spring through fall. It has vaguely daisy-like yellow flowers on long, straight stems, which attract nectar-eating insects. The plants grow 3 to 4 feet tall. Likes both shade and sun. All parts of this plant are poisonous to humans, if ingested.
