Habitat - Moist ground, low woods, slopes, roadsides, railroads, disturbed sites, waste ground.

Origin - Native to Europe.

Other info. - This little plant is one of the first to bloom in the spring and is quite striking. It prefers a somewhat shaded location and moist ground. The plant was cultivated at first but is now escaped and quite common. The flowers produce 4 nutlets each. Since it is introduced, it should not be propagated outside of cultivation.
Steyermark lists two varieties in the state. Variety hederacea has corollas to +2cm long. Variety micrantha Moricand has corollas to 1.5cm long and is much more common.
