Potentilla erecta (Tormentil)

Potentilla erecta (Tormentil) is a small, rhizomatous, clump-forming perennial forming a foliage mound of deeply cut, shiny green leaves adorned with three narrow leaflets. From late spring to late summer, 4-petaled, bright yellow flowers, 1/2 in. across (1 cm), bloom on long stalks. They are a rich source of nectar and attract bees, butterflies, and other pollinator insects. This plant is considered to be one of the safest astringents, and it is widely used in herbal medicine in the treatment of diarrhea, dysentery, and sore throats. The roots are extremely rich in tannin, and they yield a red dye, which is still used as an ingredient in the manufacture of artists’ colors.

• Grows up to 12-18 in. tall and wide (30-45 cm).
• Performs best in full sun or part shade, in average, medium moisture, well-drained soils.
• Great for herb gardens, cottage gardens, rock gardens, or border fronts.
• Virtually pest and disease free. Rarely if ever troubled by browsing deer.
• Propagate by seed. Sow early spring or autumn in a cold frame. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
• Native to Europe, northern Africa, and southwestern Asia.
