The common sunflower is one of the oldest domesticated plants in North America. Prior to European contact, various Native American tribes like the Cherokee and Dakota grew common sunflowers for food and ceremonial purposes. However, it was only in the early 20th century that commercial breeding programs started focusing on developing sunflowers solely for their ornamental value. Early cultivars were selected for traits like dwarf stature, varied flower sizes and unique colors other than the traditional yellow. This laid the foundation for today’s wide diversity of ornamental sunflower varieties.
Varieties Available
There are hundreds of varieties available nowadays in a kaleidoscope of colors from bright yellow to deep red, orange and burgundy. Dwarf varieties stay below 3 feet tall while some climbing varieties can grow 8-10 feet. Some varieties bear solitary flowers while others produce multiple branches with many small flowers. Some have plain petals arranged like a child’s drawing while others have intricate patterns, frills or quilling. Ornamental Sunflower also differ in flowering time from early summer varieties blooming in June to later ones that continue till first frost. This diversity allows gardeners to enjoy their cheery blooms throughout the growing season.
Planting and Care
Ornamental sunflowers are as easy to grow as their edible cousins. They thrive in full sun and average, well-drained soil. Seeds can be directly sown after last spring frost when soil has warmed up. Alternately, start seeds indoors 4-6 weeks earlier for an earlier bloom. Space plants 12-24 inches apart depending on the size of the mature plant. Stake tall varieties at planting. Provide 1-2 inches of water per week to established plants and divide/ transplant clumping varieties every 2-3 years.
Pest and Diseases
These hardy plants require minimal care once established. However, squirrels may dig up and eat freshly planted seeds so using mesh covers is recommended. Powdery mildew can occasionally affect late season plants during periods of cool, wet weather. Cutting off affected leaves and improving airflow helps prevent its spread. Other than that, ornamental Helianthus are generally pest and disease free.
Landscaping Ideas
Ornamental Helianthus add a cheerful, country charm to any garden. Use them as accent plants along pathways or borders. Dwarf varieties work well in containers on patios. Their bushy habits also make them ideal for cutting gardens. Taller varieties with multiple branches are striking when massed together at the back of a flowerbed. Their statuesque blooms create an instant focal point. Try combining contrasting varieties for a wild, tropical look. Ornamental Helianthus also naturalize easily, self-sowing to return reliably each year.
Ornamental sunflowers pack a visual punch with their vibrant blooms, making them a valuable addition to any landscape. Their versatility and low-maintenance needs appeal to both experienced gardeners and newbies alike. Their cheerful spirits brighten up gardens from summer through fall and bring wildlife like bees and birds. Anyone with a patch of sun can enjoy these sunshine boosters. Consider including some in your outdoor spaces to uplift your surroundings with a splash of golden color.
