Noteworthy Characteristics

Polygonatum biflorum, commonly called small Solomon's seal, is a rhizomatous, upright, arching, Missouri native wildflower which occurs in rich woods throughout the State. Typically grows in a mound to 1-3' tall on unbranched stems. Small, bell-shaped, greenish yellow flowers (usually in pairs) on short pedicels dangle in spring from the leaf axils along and underneath the arching stems. Flowers are followed by blue-black berries in autumn. Conspicuously parallel-veined, alternate leaves (to 4" long) are smooth on both sides and turn an attractive yellow in fall. Starchy, edible rhizomes were formerly used by early Americans as a potato-like food. Common name is usually considered to be in reference to the large, circular seals (leaf stalk scars) located on the rhizomes. However, Edgar Denison suggests that the name actually refers to "wound sealing properties" of the plant.

Genus name comes from Greek words poly meaning many and gonu meaning knee joint in reference to the jointed plant rhizomes. Early herbalists believed that plants with jointed rhizomes were helpful in treating human joint disorders.

Specific epithet means twin-flowered.

Problems

No serious insect or disease problems.

Uses

Best in woodland gardens, wild gardens, naturalized areas or native plant gardens. May be used in partially shaded borders or rock gardens. Good with astilbe and ferns.
