Solomon's Seal, the common name for a genus of herbaceous, perennial plants. There are about 50 species, native to temperate regions of the Northern Hemisphere. The long, curving, unbranching stems rise out of the ground from rootstocks (underground stems). The oval or lance-shaped leaves are borne only on the upper part of the stem. The small, white or greenish-yellow flowers are bell-shaped.
The name Solomon's seal is derived from the scars left on the rootstocks when the stems die down at the end of a growing season. These scars somewhat resemble the impression of a seal upon wax.
Many species are common North American wildflowers. One species of the eastern United States grows from one to three feet (30 to 90 cm) high and has lance-shaped leaves up to four inches (10 cm) in length. The flowers, about one inch (2.5 cm) long, are greenish yellow.
Solomon's seals make up the genus Polygonatum of the butcher’s broom family, Ruscaceae. The common wildflower of the eastern United States is P. biflorum.
