Habit: This winter annual flowers from March through May. Plants are often problematic during turfgrass seedling establishment and may occur in large numbers during the spring after fall tillage.

Leaves: Plants are small and leaves form a basal rosette about 2 inches (5 cm) in diameter. Leaf margins are smooth or with occasional toothed indentations. Leaves are oblanceolate and tend to taper slowly toward the point of attachment.

Identifying Characteristics: Plants consist of small rosettes between the size of a quarter and half dollar and produce naked branched flowering stalks with tiny white flowers and flat green fruit. Unlike the other members of it's genus, Draba verna does not produce leaves on the flowering stems.

Flower Seed Head: The white flowers form on a long slender stem, and are 3 to 6 mm in diameter, with 4 petals. Flowering stems are many branched and do not have leaves.

Fruit are initially green but turn brown in time. Each silique contains numerous ellipsoid seed that are 0.5 to 0.6 mm long.

Where Found: Plants are more commonly found in piedmont or mountain areas where they are naturalized in pastures, fields, forests, and other disturbed areas.
