The Morton Arboretum Perennial herb with a knotty, creeping rhizome 0.5 - 1 m tall Stem: upright. Leaves: alternate, short-stalked or nearly stalkless, 4 - 15 cm long, 2 - 6 cm wide, narrowly elliptic to broadly oval, parallel-veined, hairy on the smaller veins beneath. Flowers: yellowish green, 10 - 13 mm long, tubular, with six short lobes. Stamens six. Fruit: a berry, dark blue to black, 6 - 9 mm long. Inflorescences: are short clusters (racemes) of one to three flowers hanging from the leaf axils. Similar species: The similar Polygonatum biflorum differs by having hairless leaf undersides. Flowering: mid-April to late June Habitat and ecology: Frequent in moist woods and thickets. Occurence in the Chicago region: native Notes: When the leafstalk is broken away from the rhizome, the rhizome will show a distinctive scar that is said to resemble the official seal of King Solomon. Etymology: Polygonatum comes from the Greek words polys, meaning many, and gonu, meaning knee-joint, in reference to the many joints of the rhizomes. Pubescens means downy.
