The Best Sunflowers for the Birds and Bees
'Giganteus' produces heads a foot or more across (county fair alert!) on plants growing to 12 feet or more in height. It doesn't need to be staked and produces pounds of seeds (for you and the birds).
'Lemon Queen' is the sunflower chosen by the Great Sunflower Project for its annual bee count. Bees love this sunflower, which can be grown in containers. It tops out at about 72 inches tall in the ground. Find out more about the project at greatsunflower.org.
'Mammoth Grey Stripe' is huge—growing to 12 feet tall—and it produces seed that both you and the birds will love on blooms about a foot across.
