Polygonatum biflorum Common Name: = Giant Solomon's Seal (WI). Smooth Solomon's Seal (USDA). Native to Wisconsin, distributed statewide. Native to Eastern United States. White downward hanging flowers. Upper leaves support two flowers. Lower leaves produce 4-6 flowers. Berry turns blue in fall. Clasping leaves, hairless underside. Prefers part sun to deep shade conditions. Grows to 30-45 inches. Grown in trial bed: Hill.
7/7/2008: - Plants form a thick dense mass that tend to choke out other species. Clump expands from underground rhizomes as well as from viable seed. We removed this plant from our regular trial gardens as it proved to be too aggressive for our use. Great plant for a native hillside, but it does not play well with others in a typical garden bed. |
