Giant Solomon's seal (Polygonatum biflorum) is an elegant perennial plant native to North America's understory and forests. It can reach between 30 and 90 cm in height and is distinguished by its arching stems and oval, dark green alternate leaves arranged in symmetrical rows along the stems. In the spring, small, bell-shaped, cream-coloured flowers hang in pairs under the stems, exhaling a sweet fragrance. In the fall, the flowers turn into blue-black berries, adding ornamental interest to shaded gardens.
Ecological Roles
Giant Solomon's seal provides a source of food and shelter in the understory. Its berries attract certain birds and small mammals in the fall, which help disperse the seeds. Its fragrant flowers also attract pollinators, including bees and bumblebees, in spring. Planting this species in woodland gardens supports shaded ecosystem biodiversity.
Giant Solomon's seal seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
