Species Information

General:
Biennial or short-lived perennial herb from a simple stem-base; stems simple or branched above, 0.3-1.2 m tall, densely stiff-hairy at base, usually glabrous above.
Leaves:
Basal leaves oblanceolate, 3-14 cm long; stem leaves strongly overlapping, narrowly egg-shaped to lanceolate, 5-15 cm long, to 4 cm wide, unstalked and ear-like at the bases.
Flowers:
Many-flowered racemes; petals 5-6 mm long, cream sepals about 3 mm long, glabrous, not bulging at one side on the base.
Fruits:
siliques, erect, appressed to axis of the inflorescence, straight, glabrous, 6-10 cm long, 1-1.5 mm wide; seeds 1-1.5 mm wide, with very narrow wings.
Notes:
This taxon occurs in many native habitats but also readily colonizes roadsides and waste places. Its native status is therefore uncertain (Rollins 1993).
