Verbascum virgatum

Phenology Flowering Apr–Jun(–Oct).
Habitat Fields, roadsides, disturbed sites.
Elevation 10–2000 m. [0–6600 ft.]

The occurrence of Verbascum virgatum in Nova Scotia may be historic; Ruth collected specimens from 1940 through 1960 from East Chester, Sydney, and Wolfville; it apparently has not been seen there subsequently. It also may be historic in British Columbia.
