About
Cirsium rivulare 'Trevor's Felley Find' PBR is a perennial that grows in clumps, reaching heights of up to 1.2 meters. It features soft, purple-tinged stems and silvery green leaves at the base. During summer, it produces pincushion-shaped flower heads in violet-purple, with additional blooms possible if deadheaded. These flowers attract pollinators, and leaving the final blooms can yield seed heads that serve as a food source for finches.
