Helianthus pauciflorus (Stiff Sunflower) is an upright, rhizomatous perennial with rigid and hairy, green or reddish stems clad with lanceolate to ovate, grayish-green leaves, often folded lengthwise. A profusion of brilliant yellow flowers, 2-4 in. across (5-10 cm) are produced from early summer to fall. Each flower features up to 10-25 bright yellow rays surrounding a purplish brown central disk. In dry weather, the petals fold up lengthwise or become twisted. A valuable plant for bees, butterflies and birds, Stiff Sunflower can spread aggressively by rhizomes to form colonies. Found in dry or drying prairies, roadsides, and open woods, Stiff Sunflower is a delight in large perennial gardens and wildflower meadows. It is not suited to the small perennial border as it needs room to spread.

  • Excellent choice for cottage gardens, butterfly gardens, wildflower gardens, prairies and meadows.
