Helianthus debilis Thin, 4 foot stems are adorned with many dangling, 3 inch flowers in yellow, orange, and gold sunset shades, all with dark brown disks. These sunflowers are free spirits in the garden, displaying almost like sprays of wildflowers atop a semi-tall habit throughout the summer. Pollinators love their abundant blooms, which also make a beautiful addition to cut flower arrangements. Ideal for adding height and vibrant color to the back of your garden beds.
