Duration: Perennial Nativity: Native Lifeform: Subshrub General: Perennial herb, woody at the base, arising from a basal rosette, to 150 cm tall, erect to sprawling, canescent, branching above the base, stems square. Can get bushy in favorable conditions, fragrant. Leaves: Somewhat thick, deltoid to lanceolate, usually about twice as long as wide, to 5 cm long with toothed margins, the teeth somewhat widely spaced, bright green above and dusty green beneath, veins obvious on the underside of the leaf, opposite, generally not crowded. Flowers: Violet or blue, 3.5-5 mm long, tubular with a small lip and hood, tightly packed in interrupted spikes with distinct verticels, the calyx tube green or tan, stamens not or just barely exceeding the corolla, the anthers pink with purple lines. Fruits: Tiny, oblong nutlets with hairs at the apex. Ecology: Found on igneous substrates in canyons, open pine forests, grasslands, and oak woodlands, from 3,500-6,500 ft (1100-2000 m); flowers August-October. Notes: This pretty member of the mint family stands out with its interrupted but generally more open inflorescences, smaller blue flowers, and exceptionally fragrant foliage. Ethnobotany: Unknown Synonyms: None Editor: LCrumbacher, 2011 Etymology: Agastache comes from agan, "very much," and stachys, "an ear of corn or wheat," having many spikes, while wrightii is named after British botanist William Franklin Wight (1874-1954) who specialized in the flora of India.
