A beautiful, carefree perennial. 'Summer Sun' puts on a show of semi-double, 2-3 inch 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 is an excellent tall perennial for the back of the flower border. It has a bushy, well-branched form and glossy, deep green, triangular leaves. It's a real workhorse in the garden!
