Polygonatum pubescens — hairy Solomon's-seal
Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.
Facts
Hairy Solomon's-seal is distinguished from King Solomon's seal in part by the pubescence on the veins of the underside of the leaves. The rhizome is edible after cooking long enough to neutralize the calcium oxylate crystals and saponins.
Habitat
Forest edges, forests, talus and rocky slopes
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.
