Nettleleaf Sage, Wild Sage - Salvia urticifolia
|
Salvia urticifolia - Nettleleaf Sage, Wild Sage. Salvia is a large genus of around 600 species in the Mint family (Lamiaceae.) Over 90 Salvia species are found in the North America; over 20 of these are introduced. Salvia urticifolia - Nettleleaf Sage - is a species confined mostly to the southeastern part of the country, with Pennsylvania being at the northernmost extreme of its range. It is Endangered in Florida, Kentucky, and Maryland (possibly extirpated in Maryland.) It is found in dry open woods and forest edges. The ones I have encountered were near cedar glades, which are on shallow soil over limestone, providing soil tending toward basic pH, the preferred soil for this species.
Found in:
AL, DC, FL, GA, KY, MD, MS, NC, PA, SC, TN, VA
