Easy to Grow and Versatile

Rudbeckia Hirta Indian Summer is celebrated for its ease of growth and adaptability. It thrives in full sun and prefers average, well-drained soil, but will also tolerate poor soil conditions. Once established, it exhibits excellent heat and drought tolerance. For optimal germination, transplanting is recommended: sow seeds into plug flats 5-7 weeks before planting out, covering them very lightly as light is needed for germination. Bottom water or mist to avoid covering the seeds. Direct sowing is also possible with a very light covering of the seeds. Pinching is not required, and this variety will readily reseed. It makes an excellent cut flower, bringing its sunny exuberance indoors. Plant in a sunny location with 12-18″ spacing to allow for its vigorous growth.
