Facts

Virginia stickseed inhabits moist deciduous forests, usually in areas of high-pH substrate. It was important in Cherokee herbal medicine. The crushed roots were mixed with bear oil and used to treat skin cancers, a tea of the plant was used to treat kidney conditions and improve memory, and the plant was used in love charms.

2.  Hackelia virginiana (L.) I.M. Johnson N

Virginia stickseed. Lappula virginiana (L.) Greene; Myosotis virginiana L. • CT, MA, NH, VT; also reported from RI by Magee and Ahles (1999), but specimens are unknown. Mesic, deciduous forests, talus, cliff bases, usually in regions of high-pH bedrock. Reports of this species in ME by Fernald (1950b) are erroneous and based on Hackelia deflexa.

Native to North America?

Yes

Sometimes confused with

Hackelia deflexa:
mericarps with a single row of glochids on each margin, sometimes with 1–3 small glochids on the outer surface, and basal leaf blades narrow-ovate to oblanceolate (vs. H. virginiana, with mericarps with 10–25 glochids on the outer surface that are of similar length to the marginal glochids and basal leaf blades broad-ovate to cordate-ovate).

  • Lappula virginiana (L.) Greene
