Agastache urticifolia

Nettleleaf Horsemint

Erect cluster of stems, strong odor. Stems branched or not, more or less square, with 4 edges. Leaves broadly lance-shaped, 1–3 in. long, with sharp teeth, lighter green on underside. Flowers in dense spike 1–6 in. long, leaf-like bract at base. Flowers are open tubes, upper 2 lobes shorter than 3 lower lobes, violet to rose or white. Grows in woodlands, moist to dry meadows, open slopes, at low to high elevations. Plants near the coast are hairier than those inland. Agastache occidentalis has similar deep rose-violet flowers in spike above leaves, but usually unbranched stems, leaves with hairs and no sharp teeth; common in Yakima River and other rocky canyons east of Cascades. Agastache is Greek for "many spikes."
