PhenologyFlowering and fruiting May-July.
IdentificationSchweinitz's Ragwort grows to about 2.5 feet tall. Its basal leaves are distinctive: lance-shaped or narrowly ellitpical, with a rather squared off or slightly cordate base and small marginal teeth. The stem leaves are essentially pinnately cut on their lower halves. P. paupercula is similar, but its basal leaves are tapered to the base. Despite relatively few NC locations, where it occurs it can be very numerous, and in full bloom can coat a grassy bald in golden yellow flowers.
Taxonomic CommentsIn older works, treated as Senecio robbinsii.
