Helianthus giganteus – Tall Sunflower – 2-Quart


A towering plant when full grown, with loose branching panicles of 2” flowers toping rough hairy stems. The flowers are a favorite of bumblebees and the seeds are eaten by birds. Spreads by rhizomes at a mild pace that won’t overwhelm surrounding plants. Also known as Swamp Sunflower – it’s a wet meadow species in the wild – we have grown it under average to dry garden conditions and it has thrived. The species is native throughout most of eastern North America; in New York it’s most common in the southeastern portion of the state,  including right here in Ulster County.
