Summary edit

Description

Parietaria pensylvanica 6/2021 Pennsylvania Pellitory- (Native) Pennsylvania Pellitory, Mature size: 6-12in., Leaves are thin, 1 to 3 inches long, up to ½ inch wide, mostly lance-shaped with a blunt or pointed tip, toothless, sparsely hairy, on a stalk up to 1 inch long, alternately attached, USDA Hardiness Zone HA, Michigan Bloom Month -, In Garden Bed W1 for 0 DAYS (Native). Planted in 2021.

Minn Wildflowers: Pennsylvania Pellitory is generally considered a (native) urban weed, popping up in disturbed soil along the sides of buildings, woods and thickets, and gardens. It has a preference for light shade and can form colonies where there is little competition. I first noticed it in my own suburban back yard after clearing out an area to plant new shrubs. It is a persistent annual but not very aggressive like invasive species are. It is similar in structure to Three-seeded Mercury (Acalypha rhomboidea) which is a larger plant with toothed leaves. It is also in the same family as Stinging Nettle, but does not have stinging hairs.
