Each 'Mongolian Giant' plant produces a single yellow flower up to 18" across that will provide extra-large seeds filled with tasty, hearty kernels. These single-stem sunflowers attract pollinators and are very easy to grow in almost any sunny garden, although a sunflower's size is dependent on the growing conditions. They also are drought tolerant and fast growing; you can almost watch them gain an inch or more a day! Inside this packet, we've included tips on how to protect your ripening seeds from squirrels and birds, and a recipe for roasting seeds. Edible, bittersweet petals make a sunny garnish on salads and appetizer plates.
