A beautiful, carefree perennial. 'Summer Sun' puts on a show of semi-double, 2-3" wide, bright gold flowers all summer long. Their strong stems make them great for cutting. This variety of heliopsis is very heat tolerant, making it the best cultivar for southern zones.
Heliopsis have traditionally been an excellent tall perennial for the middle or back of the flower border. It has a bushy, well-branched form and glossy, deep green, triangular leaves – a real workhorse in the garden! Use this plant in combination containers, as a cut flower, or to attract butterflies to your garden.

Heliopsis can be grown in either full sun or part shade, but it performs much better in full sun. Soil of average fertility is preferable. When grown in moist, rich soil, it tends to need staking. Growth will be strongest in soil with average fertility and moisture.
Deadheading spent flower heads will extend the flowering time and prevent self-seeding. Divide every 2-3 years in spring or fall to maintain vigor.
