Uses and Benefits: Heliopsis 'Summer Sun' is perfect for the back or middle of sunny borders, prairie-style plantings, and pollinator gardens. Its long bloom time ensures colour throughout the growing season, while its upright habit adds height and structure. Bees, butterflies, and other beneficial insects flock to its flowers, making it a valuable addition to wildlife-friendly landscapes. It also makes an excellent cut flower for bright, cheerful arrangements.

Companion Plants: Pair Summer Sun with Echinacea 'Cheyenne Spirit', whose mix of warm-toned blooms complements the golden-yellow flowers while echoing the prairie aesthetic. Add Rudbeckia triloba, whose smaller yellow daisies provide a layered, wildflower look and extend the bloom season. Complete the planting with Schizachyrium 'The Blues', whose silvery-blue blades and purple fall hues provide vertical texture and contrast.

Care Instructions: Plant in full sun with well-drained soil. Water regularly during establishment; mature plants tolerate drought well. Deadhead spent blooms to encourage continuous flowering, or allow seed heads to develop for bird interest. Cut back in late fall or early spring. Divide every 3–4 years in spring to maintain vigour and manage clump size.

Celebrated for its reliable flowering, it has become a garden staple—particularly in cottage and wildflower-inspired plantings—offering the charm of sunflowers in a perennial form that doesn’t require replanting each year.
