Sunflowers are some of the most recognizable and iconic annual flowers in the world. Produce from this plant, namely sunflower oil and seeds, carry great culinary and nutritional values. These would be vivid additions to a garden with oversized flowers that bring the colors of the sun closer to you.
Helianthus annuus are beloved summertime flowers that bloom from mid-summer to early fall. With their broad central disks and short, yellow petals, these flowers typically measure 3 to 6 inches (7.5-15 cm) across, being the main identification feature of the plant. Growing on tall, sturdy stems, sunflowers can have single or multiple blooms. Their rough, hairy leaves are oval to triangular in shape. Being annuals, sunflowers complete their life cycle within a year.
