PhenologyFlowering and fruiting July-October.
IdentificationBurdocks (Arctium spp.) are thistle-like plants, at least with the inflorescences -- numerous purple to rose-colored flowers, all with disk corollas only, and usually spiny bracts. Greater Burdock differs from A. minus in having long stalks to the heads (vs. very short in the latter). It is told from A. tomentosum by its broader heads and sparsely cobwebby phyllaries (vs. densely cobwebby in that species).
