Latin name: Draba verna

Family:  Brassicaceae

Common name:  whitlow-grass

Life cycle: annual, reproducing by seed
Habit:  Forms a very small prostrate basal rosette (1 to 2 inches wide).  From the basal rosette a leafless raceme emerges and grows upright to 6 inches tall.
Foliage:  Only basal foliage which is small (1 to 2 inches long), pubescent with star shaped hairs, and from green to purple in color.
Flower:  Flowers occur in a raceme (typical of mustards), with each flower having 4 white petals.  Flowers are small (1 to 3 mm across).
Seed pods:  Flattened, football shaped, about 3 mm long.  These can be used to distinguish this plant from Arabidopsis and Shepherd's purse.

Notes:  This plant is small, inconspicuous, and typically flowers and disappears before April.  Therefore, it is not a plant that requires any attention in terms of weed control.  It is included on this website for thoroughness, because it does occur often and in high numbers in cultivated fields of western Oregon.
