Netteleaf Horsemint

Agastache urticifolia is one of the mint family that is known for the square stem. Horsemint grows in open areas of high elevation ridges and forested sites that are commonly overgrazed. Over grazing can at times cause a dense stand of this spike like perennial herb to take over the site, although it is fair in forage value the native grasses would be a more desired species. Horsemint grows in an ascending form (obliquely upward, usually curved) to a variety of heights from 1 ½ to 5 feet depending on the environment. As with many mints, horsemints’ leaves are opposite or whorled (three or more extending from one node) extending out from the stem node.
