Gladecresses (Leavenworthia)
Description
Leavenworthia is a genus of flowering plants in the mustard family, Brassicaceae. It includes about eight species native to the southern and southeastern United States. They are known generally as gladecresses. These are small annual herbs under 10 centimeters tall. They produce a basal rosette of leaves and often lack a true stem, instead sending up a scape, a flowering stalk topped with an inflorescence. The inflorescence is usually made up of just one flower, but a large plant may produce several flowers in a raceme. The petals are white, yellow, orange, or lavender. They are often notched and clawed, narrow at the base and wider at the tip. There are six stamens, two short and four long. The fruits are siliques or silicles of various shapes. The seeds are flattened and have wide margins or wings.
