About Polygonatum biflorum

Polygonatum biflorum grows from spreading rhizomes and forms tall arching stems.

The stems are clothed with pairs of pointed oval mid-green leaves which create a layered woodland appearance.

In late spring and early summer, small clusters of tubular flowers appear beneath the leaves.

These hanging blooms are white with green tips and develop into small black berries later in the season.

The tall stems and arching shape make this species particularly striking in woodland planting.
