Description

Giant Solomon's Seal is a native herbaceous perennial wildflower found in moist forested areas and roadbanks in the eastern U.S.A. and Canada.  As its common name suggests, this is a large Soloman seal reaching heights of 3 to 5, occasionally 7 feet. 

Plant it in medium to wet average soil in partial to full shade, though it does best with some sun.  It has attractive large leaves and clusters of white bell-shaped flowers that hang down.  It will spread in the landscape through its rhizomes, but it is very difficult to propagate by seed.  

There is considerable controversery surrounding the taxonomy of great Solomon's seal including making it a variety of P. biflorum as we have here but some argue it should be its own species so the names P. commutatum, P. giganteum, and  P. canaliculatum are used to varying degrees.

Use it in a rain, woodland or cottage garden, the back of a border, or let it naturalize in your yard.  Just make sure it has plenty of room as this plant larger than other Solomon seals.

Insects, Diseases, or Other Plant Problems: No serious problems.
