Red Sun Sunflower Seeds | Heirloom | Non-GMO | Fresh Garden Seeds
Red Sun is a branching variety of Sunflower, which produces vibrant red petals, accented with a dark brown center.
Red Sun Sunflowers will grow quickly from freshly harvested seeds. The plants will produce stems, leaves, and then flowers, all within a single growing season. When the cooler temperatures of the late Autumn season arrive, your sunflowers will begin to wilt.
Before the first frost, you can gather the seeds from your plants to resow the following year. Be careful, however, as many squirrels, birds, and other animals will be after them as well.
