Rudbeckia fulgida var. 'Goldsturm'

Common name	Black eyed Susan
Hardiness Zone	3 to 9
Sun	Full sun
Soil	Dry to medium moisture
Flower color	Yellow rays with black center
Bloom Time	June - September
Height	2 to 3 feet

General Culture:
Easily grown in average, dry to medium wet, well-drained soil in full sun. Tolerates hot and humid summers and some drought. Tolerates light shade, but best in full sun. Deadhead to prolong bloom. Divide when clumps become overcrowded.
Noteworthy Characteristics:
This coneflower cultivar is an upright, rhizomatous, clump-forming perennial which typically grows 2-3' tall. Features large, daisy-like flowers (3-4" across) with deep yellow rays and dark brownish-black center disks. Flowers appear singly on stiff, branching stems in a prolific, long-lasting, mid-summer-to-fall bloom.

Problems:
A common problem of this cultivar is angular leaf spot caused by a bacterium. The disease causes brown or black angular spots on the leaves which can expand to blacken the whole leaf. Infection begins on the lower leaves and moves up the plant. Rudbeckias are also susceptible to septoria leaf spot and powdery mildew.
Uses:
Mass in bold drifts in the perennial border, cottage garden, prairie, meadow or naturalized area. Provides excellent bloom and color for late summer.
