Great Solomon's Seal, Giant Solomon's Seal Seal Flower, Polygonatum biflorum, Polygonatum canaliculatum, Polygonatum giganteum


Polygonatum commutatum (Great Solomon's Seal) is a shade-loving, rhizomatous perennial with arching stems boasting small clusters of 3-8 nodding, tubular, yellowish green to whitish green flowers in late spring. Gracefully hanging from the leaf axils, they are followed by ornamentally attractive deep purple berries in the fall. The elegant foliage of oval to oblong, mid-green leaves, turns attractive shades of yellow in the fall. A magnificent shade-loving plant that needs space to be displayed to advantage. Outstanding on the edge of moist woodland areas.

  • Grows up to 4-5 ft. tall (120-150 cm) and spreads 2 ft. (60 cm). May reach up to 7 ft. in height if happy (210 cm). Slowly spreads by rhizomes to form colonies in optimum growing conditions.
  • Best grown in part shade to full shade in fertile, humus-rich, moist, well-drained soils. Prefers cool sun-dappled shady areas and dislikes hot summer conditions.
  • Perfect for shade gardens and woodland gardens. A great companion plant to other shade lovers including hostas, ferns, and astilbes.
  • Virtually pest-free, disease-free and low maintenance but watch for slugs.
  • Propagate by division in early spring or in the fall.
  • All parts may cause severe discomfort if ingested
  • Native to eastern North America.
