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.

'Mongolian Giant' needs rich soil and full sun to reach its full height. This tall plant may need staking when it reaches taller heights.
