Description

Erysimum ammophilum is a biennial or perennial plant varying in size from a few centimeters to over half a meter in height. It starts from a patch of long, narrow dark green leaves and produces one to several erect stems lined with similar leaves.

Atop the stem is an array of bright yellow flowers, each with four rounded petals. As the stem grows the flowers drop away to leave developing fruits, which are narrow siliques 2 to 12 centimeters long sticking out from the stem. The fruits contain winged seeds.
