Duration: Perennial Nativity: Native Lifeform: Subshrub General: Herbs to 60 cm tall with a woody caudex, numerous erect stems, 2-3 mm in diameter at midpoint. Leaves: Lanceolate, 1.5-4.5 cm long, pale green above, gray-green below, the blades mostly 2.5-3 times longer than wide, base truncate to acute, serrate margin, acute apex. Flowers: Continuous spike 8-10 cm long, with 10-15 verticils; calyx green to tan, 2.5-3.5 mm long, the tube 2 mm long, not appearing folded, the secondary costae thinner than or equaling the primary costae or indistinct; corolla tube 2.5-3.5 mm long, white; stamens and pistil slightly exserted. Fruits: Nutlets about 1 mm long, 0.5 mm wide, ovoid to oblong, light brown, with hairs in upper half. Ecology: Found on granitic outcrops, along washes in oak-grassland and pinon juniper zones from 5,000-7,500 ft (1524-2286 m); flowers August-October. Notes: Told apart from other Agastache by its continuous spike, its minute flowers, and its leaves that are much longer than wide. Purported to be at Tonto NM, but there is some question as to the validity of this, due to the range of the species. Collect this species or genera for further clarity. Ethnobotany: Unknown, but other species in this genus have a variety of medicinal uses. Etymology: Agastache is from Greek agan, very much, and stachys, an ear of corn or wheat, in reference to the spikes of the plant, while micrantha means small flowered.
