Semi-woody, profusely branched, erect perennial; stems 20-100 cm long; leaves ovate, lanceolate, or elliptic, 2-3 times longer than wide, 8-12 mm long, grayish green because of light pubescence especially on lower surface; flowers rose-pink, 12-25 mm long, in whorls in compact spikes, zygomorphic, petals 5, fused into a tube, the two small upper petals extending forward much like the visor of a cap, the three larger lower petals forming a reflexed lip; fruit dividing into 4 dark nutlets each about 2 mm long. Flowers June to September.
There are several species of Agastache in New Mexico. Agastache cana has the following combination of characters: calyx tube longer than 3 mm, the upper calyx teeth 1/4-1/2 the total length of the calyx, the stems slightly woody with the bark peeling at the base of the stem, and leaves 2-3 times longer than wide.
New Mexico, Dona Ana, Grant, Luna, and Sierra counties; Texas, El Paso and Hudspeth counties.
Crevices and bases of granite cliffs or in canyons with small-leaved oaks at the upper edge of the desert and lower edge of the piñon-juniper zone, at 1,400-1,800 m (4,600-5,900 ft).
Clearly this is a regional endemic. It occurs in areas not easily accessible to collectors, development, or even domestic livestock (if they utilize this species). There are no apparent threats to the species under current land uses.
