Shepherdspurse Flowers |
|
Shepherdspurse is an annual with erect
stems that grow 3 - 18 inches tall from a basal rosette. Small white flowers are present
at the end of long racemes (flowers arranged along a stem on individual stalks) early
spring - September. Fruits are flattened and heart-shaped. A single plant may produce over
1,000 long-lived seeds. Seeds germinate early spring, summer, and early fall. Cotyledons
are egg-shaped. Young rosettes have variable degree of lobes on the leaves and older
leaves are more deeply lobed. Plants die soon after fruiting. Common in mint,
wheat, alfalfa, and cultivated vegetables, and along roadsides and waste areas. |
