The prevalent species of Digitaria in North America are large crabgrass (D. sanguinalis), sometimes known as hairy crabgrass; and smooth crabgrass (D. ischaemum). These species often become problem weeds in lawns and gardens, growing especially well in thin lawns that are watered lightly, under-fertilized, and poorly drained.
The flowers of smooth crabgrass grow in clusters of 2 to 6, forming spike-like shapes about 1½ to 4 inches long, arranged like fingers at the tips of branching stems. The flower spikelets are small, egg-shaped, and come in pairs along the stem, with one on a short stalk and the other on a longer one. Each spikelet has one fertile flower.
