The narrowleaf black-eyed Susan is a southeastern native variety prized for its slender foliage and golden daisy-like flowers that brighten gardens from summer into fall. It thrives in part shade to full sun with average moisture and adapts well to sandy or well-drained soils common in Gulf Coast gardens. Minimal deadheading and an annual cutback in late winter are all it needs to stay tidy and vigorous.
