    To identify P. virginianum, note the slight hairyness (pubescence) on the stems and leaves. P. virginianum has this pubescence, whereas P. tenuifolium does not have hairs on the stem (it is glabrous). Other than that, their leaf shape/form is nearly identical.

    This plant has fragrant minty-smelling leaves, unlike its close relative Narrowleaf Mountain Mint (Pycnanthemum tenuifolium) . The tiny purple-spotted white flowers attract short-tongued bees, and many species of harmless wasps.

    This is a plant that should be grown more often. Don't be afraid to plant it because it attracts wasps. This plant does not attract yellow jackets and hornets, the dangerous wasps that attack and sting people, only the harmless wasps that eat garden pest insects. It's good to have wasps around the garden.
