Botanic information
Leaf: The oblong to ovate leaves have an acute apex and the quilted textured upper surface that is covered in fine silvery hairs. They have an entire to crenulate margin with a short petiole and when crushed the leaf is aromatic. 

Flower: The pubescent labiate flowers have a dark purplish calyx with pointed lobes and a blue, pink or white 2-lipped corolla. The flowers are arranged in a terminal or axillary raceme that is held above the foliage on a leafy scape from late spring to early summer.

Fruit: The tiny nutlet develops inside the calyx and produces viable seed but the plant is commonly reproduced vegetatively.
