Annuals, Edible Plants

Hairy bittercress is a winter annual or biennial plant in the mustard (Brassicaceae) family native to Europe and Asia, but also present in North America. It is commonly found in damp or disturbed soil. It has a basal rosette and may form a dense mat.

The bright green leaves generally contain 4 to 8 leaflets arranged alternately along the rachis. The stems of the plant are hairless and the leaves remain green even through winter months. The plants are food for the larval (caterpillar) stage of a few early butterflies, including (in the United States) spring azure (Celatrina landon) and falcate orange-tip (Anthocharis midea). 

Small white flowers occur in racemes with individuals containing four petals. They appear on wiry stems from early spring until fall. Like many brassicas, hairy bittercress has a dehiscent seed pod which contains seeds that explode out at the slightest touch. Once it is etablsihed in a lawn, it is difficult to eradicate. It is a favorite plant of aphids.
