Summer Sun False Sunflower
Heliopsis helianthoides var. scabra 'Summer Sun'Summer Sun False Sunflower is a vigorous native perennial prized for its large, fully double golden-yellow flowers, sturdy upright habit, and exceptionally long bloom season. Beginning in early summer and continuing into early fall, abundant sunflower-like blooms with layers of bright golden petals cover strong, branching stems, creating a bold display of color in the landscape. The long-lasting flowers attract bees, butterflies, and other beneficial pollinators while also making excellent additions to fresh-cut bouquets.
Its upright, clump-forming habit makes Summer Sun an outstanding choice for perennial borders, cottage gardens, prairie-style landscapes, and pollinator gardens. The large blooms create a striking focal point and pair beautifully with ornamental grasses and other late-season perennials. Strong stems help support the heavy flowers, allowing the plant to maintain its impressive appearance throughout the growing season.
Typically growing 4 to 5 feet tall and 2 to 3 feet wide, Summer Sun thrives in full sun and well-drained soil. Once established, it tolerates heat, humidity, drought, and a variety of soil conditions, making it a dependable, low-maintenance perennial for sunny landscapes. Leaving the seed heads in place after flowering provides food for birds well into fall and winter.
