Description
Black‑eyed Susan (Rudbeckia hirta) is a cheerful biennial wildflower that grows 1–3 feet tall and blooms from June through October across most of the U.S. and much of Canada, featuring bright yellow petals and a dark central disc that draw in butterflies, bees, and birds. It thrives in full sun and well‑drained soil—though it will tolerate partial shade and occasional moisture—and is prized for its drought and heat resistance, deer tolerance, and its knack for self‑sowing at the end of its two‑year cycle. While it can spread vigorously under ideal conditions, proper drainage and occasional thinning will keep it in check.
