Nursery contributed plant descriptions

This special strain of good ol’ R. triloba has a mixture of reds & rusts that are oh-so autumnal & warm. A butterfly MAGNET, this Midwestern native grows 3-6’ tall by 2’ or more wide & is considered a short-lived perennial, though it self-sows modestly. If you don’t know R. triloba, prepare to be impressed! The flowers are small (2” across) but profuse. At peak bloom (late Summer or Fall) an established plant can produce 100’s of flowers, MORE per plant than any other Rudbeckia I can think of. This seed strain is not 100% consistent, so the shade of red may not be exactly as pictured & there are some yellow & yellow-red bicolors in the mix. But we do so love the little surprises you get from growing things from seed! OK with poor soil, heat & more shade than most Rudbeckias. Great cut flower!
