PhenologyFlowering and fruiting May-July.
IdentificationWoodland Black-eyed Susan and Weedy Black-eyed Susan are extremely similar, both up to 3 feet tall and rough-hairy on stems and leaves. Best separated by leaves (but not always successfully!): broader in var. hirta [2.5-7 cm wide vs. 1-2.5(-5) cm] and length mostly 2x width (vs. 3-5x).
Taxonomic CommentsA third variety, angustifolia, has been collected in NC on Fort Bragg in Hoke and Cumberland counties. However, both collections are from highly disturbed sites and likely are adventive here in NC; we will treat it as such.
