Notes: This lovely plant is also called the Arizona Hummingbird mint, and does justice to the name. Distinguished by the deltoid-ovate to lanceolate leaves with dentate to serrate margins and the corolla tube 6-7 mm long, some other Agastache are longer than 7 mm. 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 breviflora means short-flowered.
