Rudbeckia lacinata


Perennials, Flowers

RUDBECKIA

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 lacinata

This perennial species can reach 10 ft. tall and 4 ft. wide; it has light green, deeply lobed leaves to 4 in. long and blooms from summer to fall, bearing 2–3 1/2-in.-wide flowers with drooping yellow rays and a green cone. More widely grown in gardens are the following two selections. ‘Goldquelle’, with double blooms in lemon yellow, is a less aggressive form growing to 3 ft. tall and 1 1/2 ft. wide. ‘Herbstsonne’ (‘Autumn Sun’) grows to 6 ft. tall and 2 ft. wide; bears single, 4–5-in.-wide flowers with yellow rays and a bright green cone that ages to yellow.
