Description

This pretty yellow flower likes to get its feet into moist soil but not overly wet soil.  It tolerates many soil types, though prefers rich loams.  Flowers appear in May and June, bringing a burst of yellow color in the first months of summer.  Find it in the landscape in flower gardens as a cultivated herbaceous perennial or naturally as a weed in disturbed areas, it naturalizes in the mountains.  It grows best in shady sites though can tolerate full sun in cooler climates.

While Chelidonium majus is part of the poppy family, and its 4 parted showy yellow flowers can be mistaken for buttercups or Ranunculus.  This biennial herb has orange-yellow cell sap and a brittle stem.
