History: Heliopsis, commonly known as False Sunflower, is a native North American perennial that has become a garden staple for its long-lasting, cheerful blooms. The 'Summer Sun' variety is particularly adored for its robust growth and golden-yellow flowers that resemble sunflowers. These perennial plants have been historically used for various purposes, including ornamental, medicinal, and even spiritual in certain native cultures. The Heliopsis 'Summer Sun' variety has been bred for stronger stems and more abundant blooms, making it a modern favorite among gardeners.
Uses: Heliopsis 'Summer Sun' is incredibly versatile, both as a garden plant and as a cut flower. In gardens, its bright yellow blooms are known to attract butterflies and other pollinators, thus contributing positively to local ecosystems. They can serve as back-of-the-border plants in flower beds, or as an accent in wildflower gardens. When used as cut flowers, they bring a burst of sunshine indoors and are well-suited for both casual and formal arrangements. These flowers are also long-lasting when cut, making them ideal for extended display. They're perfect for public gardens, cut flower gardens, and educational botanical endeavors.
Growth Habit & Planting Instructions: Heliopsis 'Summer Sun' is known for its easy-to-grow nature. These plants are tolerant of a variety of soil conditions but prefer well-drained soil. To start, sow the seeds indoors 6-8 weeks before the last frost date, or directly sow them in the garden in late spring to early summer. If starting indoors, transplant the seedlings after the danger of frost has passed and the soil has warmed up. Space the plants 2-3 feet apart to ensure ample growth room. Water moderately but consistently, especially during dry periods. Although the plants are drought-tolerant, they perform best when adequately watered. No rigorous fertilization is needed; however, a balanced fertilizer can be applied in early spring for optimal growth. Pruning is minimal but deadheading spent flowers can encourage further blooming. The plants generally grow to 3-4 feet in height and spread 2-3 feet, making them perfect for adding structure and height to your garden. With the right conditions, expect blooms from mid-summer through early fall.
