Helianthus annuus. This selection of our loveliest short-growing sunflower seeds allows you to try more than one variety. Ideal for small city gardeners, they can also be grown in containers. The Short Blend Sunflowers contain a variety of field grown sunflowers ranging from 60-120cm (24-48″) tall. Plant and enjoy all these lovely, height-challenged sunflowers. Even when they’re small, sunflowers are extremely attractive to pollinators, so they are perfect for the edge of the organic vegetable garden, and will bring in scores of honeybees and other beneficial insects. Though their tiny seeds are, in theory, edible, they make better food for the wild birds that will frequent the garden in late summer.
