Heliopsis

Sun-loving, easy to grow, hardy, heat and drought tolerant, False Sunflowers (Heliopsis helianthoides) have plenty of qualities and appeal! Valuable additions to the landscape with their profusion of bright golden daisies (2-3 inches wide, 5-7 cm) on display for 6 to 8 weeks all summer until early fall, they also feature a lovely foliage that is pleasant to the eye. Use them to brighten up a sunny area of the garden or in a vase where they will last a couple of weeks!Variegated Heliopsis have long been popular in the perennial landscape, and ‘Sunstruck’ fills the spaces at a much shorter height. 2” large, golden yellow flowers appear above the cream and green variegated foliage even earlier than typical Heliopsis, and blooms all through summer until fall. Compared to ‘Loraine Sunshine’, ‘Sunstruck’ is more compact, has more ray florets and a deeper flower color. This is the perfect height for smaller spaces in the garden or for combination containers. From Darwin Perennials.

Tuscan Sun is heat tolerant and will tolerate somewhat dry soils. While deadheading may encourage additional blooming it isn't strictly necessary for a long bloom season. The breakthrough here is an easy flowering Heliopsis with a shorter plant size, outstanding garden performance and disease resistance. A long known great garden plant with good manners and a long flowering season, also makes a great cut flower!Heliopsis helianthoides, variously dubbed Early Sunflower, Sweet Smooth Oxeye, False Sunflower and other common names, is a member of the Aster family. Unlike true sunflowers and most asters, both its disk and ray flowers are capable of producing seed. It blooms profusely through the summer on thin stems above the foliage, in the manner of Rudbeckia. (Source: www.prairiemoon.com)
