Genus: Agastache

Agastache (giant hyssop) is a genus of aromatic flowering herbaceous perennial plants in the family Lamiaceae, native to eastern Asia (one species) and North America (the rest).[1][2][3][4]

Most species are very upright, 0.5–3 m tall, with stiff, angular stems clothed in toothed-edged, lance shaped leaves ranging from 1–15 cm long and 0.5–11 cm broad depending on the species. Upright spikes of tubular, two-lipped flowers develop at the stem tips in summer. The flowers are usually white, pink, mauve, or purple, with the bracts that back the flowers being of the same or a slightly contrasting color. Leaf tips can be eaten and made into teas.

"Agastache" is Greek for "many spikes".[5]
