Discussion

Subspecies dodecandra is smaller-flowered than the other subspecies and is most often found in northeastern and midwestern states. ‘White Spider’ is a cultivar sometimes offered in seed catalogues. Occurrences in New England (except Vermont) probably represent adventives from farther west; this plant is common along weedy roadsides.
