Bride's Bonnet, Queen Cup, Bead Lily
Liliaceae (Lily Family)
Synonym(s): Smilacina borealis var. uniflora
USDA Symbol: CLUN2
Each rosette of 2-3 oblong, glossy-green leaves, up to 6 in. in height, bears a short flowering stalk with one or two open, bell-shaped, white flowers. 1 (rarely 2) white, star-like flower blooms on a short leafless stalk that grows from a basal cluster of 2 or 3 oblong or elliptic, shiny leaves. Each flower is followed by a single, amethyst-blue berry. This is a spreading perennial and serves as a ground cover.
Generally there are several clusters of leaves in a patch, for the plant produces an extensive system of underground stems.
