''Pycnanthemum incanum'', the hoary mountainmint, "mountain mint", wild basil or hoary basil, is a herbaceous perennial in the mint family, widespread across eastern United States and Ontario.〔(Kew World Checklist of Selected Plant Families )〕〔(Biota of North America Program 2013 county distribution map )〕 It is listed as an endangered species in Vermont and New Hampshire, as well as in Ontario, where there are only two remaining populations located within a single stretch of oak savanna in Burlington. There is currently a recovery strategy in place organized by the Ontario Ministry of Natural Resources to monitor these last populations. It grows to high by 4 feet wide. The stems are covered with a soft, whitish down. White blooms appear from July to September. ''Pycnanthemum'' means "dense flower-clusters" in Greek, and the flowers are favored by butterflies, moths, and some species of wasps. A vigorous and often aggressive grower, this plant spreads by long rhizomes. It prefers rocky, gravelly or sandy soil, and typically grows in woods, thickets, fields, and hills, presumably the origin of its common name of Mountainmint. ;Varieties〔 # ''Pycnanthemum incanum'' var.
