Sunflowers are known as the friendly giants of the garden, adding bold, cheerful color in the summer months and attracting a parade of pollinators as they bloom. At the end of the season, harvest seeds for snacking, birdfeeders, or future planting. There are a wide range of varieties, from dwarf to wild and everything in between, making it easy for almost any gardener with a sunny spot in the garden to grow these classic favorites.
