Also known as Ashe’s savory, Ashe’s calamint is a state-threatened, perennial deciduous shrub. Its many tubular-shaped flowers are pale lavender; each has a white patch and dark purple dots. Petals and sepals are two-lipped. Leaves are narrow, with revolute margins and a bluish- to grayish-green hue. They are oppositely arranged. When crushed, the leaves emit a strong basil-like aroma. Fruit is a nutlet.



Ashe’s calamint typically blooms in spring but can bloom from January into late summer or early fall. It occurs naturally in scrub and sandhills and is attractive to insects, specifically bees, which are its primary pollinator. The plant is allelopathic, which means it emits a chemical that inhibits the growth of other plants.



The plant’s common name and species epithet refer to William Willard Ashe (1872-1932), a botanist and forester who published over 500 plant names.
