Hyptis emoryi Torr.
Desert lavender, a member of the mint family, is native to the southwestern United States and northern Mexico, found at elevations below 3000' (914 m). It is a perennial, but it drops its leaves if it is too cold.
Identification: This shrub has multiple gray stems that are square in cross-section, and is 6-15' (1.8-4.6 m) high. Leaves are oval, up to 2½" (6.3 cm) × 1" (2.5 cm), feltlike, covered with fine hairs that make them look gray-green, with fine-toothed edges. When crushed, the leaves have a strong smell of lavender or sage with a touch of honey. Flowers are lavender-colored or sometimes a brighter violet. Individual flowers are ½-1" (1.3-2.5 cm) around, with five petals. They occur in clusters.
