Summary
Brown-eyed Susan (Rudbeckia triloba) is a bushy, free-flowering, 2-3’ (up to 5’) tall biennial or short-lived perennial that readily self–sows and is very effective for naturalizing. It features masses of 1-2” wide, daisy-like, golden-yellow flowers with flat, purplish-brown centers on hairy stems from late summer to early fall. The thin, rough textured upper leaves are oval to lance-shaped and sometimes three-lobed at the base. Performance is best in moist but well-drained, humus-rich soil in full sun. Perfect for an informal garden, it also makes a good flower. Plant with purple coneflower (Echinacea purpurea), spotted Joe-pye weed (Eutrochium maculatum), mistflower (Conoclinium coelestinum), smooth aster (Symphyotrichum laeve), and New York ironweed (Vernonia nov-eboracensis). Zones 4-8.
