General Description
Yerba Buena is an aromatic perennial herb borne from a woody rootstock with short ascending branches and creeping above-ground stems which often root. The stems and branches are square in cross-section. The leaves are opposite, have short petioles (stalks), are 1-3.5 cm long and oval to almost round in shape, and have bluntly toothed margins and sunken, resin filled dots on the surfaces. Flowers are borne singly on 5-15 mm long pedicels (stalks) in the leaf axils. The calyx is 4-5 mm long and tubular shaped with 12-15 nerves and 5 teeth. The corolla is tubular with distinct short upper and lower lips at its mouth; it is 7-10 mm long, white to cream or purple-tinged, slightly hairy on the outside, and bears 4 stamens on the inside. There is a single pistil with a long slender style (stalk) that has a 2-branched tip.

Flowering in July, fruiting in early August-October.

Diagnostic Characteristics
Distinguished from other mints by combination of creeping stems, bluntly toothed leaf margins, and solitary, axillary, pedicellate flowers, each with a 5-toothed calyx, 2-lipped corolla, and 4 stamens.
