Rudbeckia fulgida

Description

Rudbeckia fulgida, or Black-eyed Susans, are some of the most popular, toughest and most beautiful perennials grown today. The cultivar 'Goldsturm' is very desirable, having compact growth and prolific flowering. Black-eyed Susans bloom in summer, but if cut back after flowering, a second, much smaller bloom may occur in late fall. 

This showy daisy-like perennial grows up to 3 ft tall with numerous flower heads, each a little less than 3 inches across. Each flower is composed of 10 to 20 yellow-orange florets surrounding a purple-brown center, hence the name.

Blackeyed Susans are easy to grow, thriving in any but soggy soils. It does best in full sun but tolerates partial shade. It also bears up under hot, humid summers and, once established, will tolerate drought. The plant spreads by underground stems called rhizomes to form large clumps. Propagation can be done by division in the spring or fall, or it can be propagated by seed. A rosette of leaves that originate at the base of the stem persists through the winter, creating an attractive winter ground cover.

This plant is occasionally damaged by deer but has been found to be moderately resistant.

Fire Risk: This plant has medium flammability rating. Consider plants with a low flammability rating for the sites nearest your home.
