About plant names...

Dakota verbena is native to the American southwest. It appears in fields, grasses, and scrublands.

Plants: Plants are annuals or short-lived perennials, 4-16″ (10-40 cm) tall. They are variable, sometimes low and matted, sometimes taller. They may cover wide expanses of ground. Stems are branched and ribbed, and purple or green; and both stems and leaves are hairy.

Leaves: Opposite, twice pinnate, thick, dark or gray green, hairy, up to 2½″ (6.3 cm) long. (Technically the leaves are pinnatifid, that is, the divisions don’t reach all the way to midveins.) Leaves are rolled under, and have deep veins.

Flowers: Rounded, almost spherical clusters of pink, lavendar, or purple flowers, about 2″ (5 cm) around. Each flower has five notched petals and a thin tubular throat (the corolla) up to ½″ (1.5 cm) long. The calyx of each flower in this variety is densely covered with glandular hairs, while G. bipinnatifida var. bipinnatifida lacks glands. They appear from February to October.

Fruits: Four nutlets, each 1/16-⅛″ (2-3 mm) long.
