About Nettle Leaf Giant Hyssop (Agastache urticifolia) Agastache urticifolia is a species of flowering plant in the mint family known by the common name nettle-leaf giant hyssop. It is native to western North America from British Columbia to California to Colorado, where it grows in many habitat types. This is an aromatic perennial herb growing an erect stem with widely spaced leaves, each lance-shaped to nearly triangular and toothed. The leaves are up to 8 centimeters long and 7 wide. The flower cluster is a dense spike of many flowers. Each flower has long sepals tipped with bright purple and tubular corollas in shades of pink and purple. The fruit is a light brown, fuzzy nutlet about 2 millimeters long. The plant was used medicinally by several Native American groups, especially the leaves.
