These big, warm-colored daisies are stalwarts of the summer and autumn garden. Descended from wild plants native mainly to the eastern U.S., all are tough and easy to grow. Blossoms have yellow or orange rays and a raised central cone. They make good cut flowers; cutting encourages rebloom late in season. Divide perennials when they become crowded, usually every few years.Rudbeckia fulgida
Perennial. Initially to 3 ft. tall and 2 ft. wide; after a few years, spreads by rhizomes to form a larger clump. Branching stems; broadly lance-shaped, 5-in.-long, hairy dark green leaves. Yellow, 2–2 1/2-in.-wide flowers with black to brown central cone bloom in summer.
Varieties are more often grown than the species. ‘Early Bird Gold’ has an especially long bloom season, running spring to fall. R. f. sullivantii ‘Goldsturm’ bears 3-in., black-eyed yellow flowers on 2–2 1/2-ft. stems.
