Plant Common Name

Goldsturm Black-Eyed Susan, Orange Black-eyed Susan, Orange Coneflower

General Description

Goldsturm black-eyed Susan, a perennial that everyone knows and loves. This easy to grow compact ornamental originates from eastern North America and packs a punch of golden garden color in late summer. Basal clumps of hairy, medium green leaves give rise to long leafy stalks topped with golden yellow daisies punctuated with black eyes. Plants are rhizomatous and may form large colonies over time. This vigorous cultivar was the Perennial Plant Association's 1999 perennial plant of the year and is one of the most highly planted perennials on the market.

In the wild, black-eyed Susan inhabits grasslands and prairies, so it grows best in sites with rich soil and full sun. This fine perennial looks best when massed in mixed borders with other sun-loving perennials and ornamental grasses. Many pollinators are drawn to black-eyed Susan flowers, to include butterflies and bees. The dry, black, button-like seedheads of this plant may be left uncut to provide winter interest and seed for birds.
