Summary
Native to North America, this shade-loving perennial has glaucous foliage with basal leaves and underground storage organs, and produces a tall inflorescence that is a raceme or panicle of white to green-brown flowers with an unpleasant odor that are poisonous; it commonly grows on shores of lakes and on cliffs, ridges, and ledges.
Prefers moist, well-drained soil with pH 6.0–7.0 and shade throughout; planting depth 1–2 inches and spacing 12–18 inches; keep soil consistently moist with weekly watering, increasing in dry spells; apply balanced slow-release fertilizer in early spring and mid-season; prune late winter or early spring and mulch with pest monitoring. Propagation by seed (sow 1/4 inch deep; 14–30 days germination) or division in early spring or fall; mature height 24–36 inches, spread 18–24 inches; roots fibrous 12–18 inches deep; used ornamentally, particularly in alpine or gravel garden planting schemes.
