Kong Sunflower

This amazing cultivar can reach up to 15 feet in height and produce flowers up to 10 inches in diameter starting in mid-summer and continuing for six weeks into fall. Good retention of lower leaves and stout, sturdy stalks supported by a strong root system are favorable characteristics in the landscape setting. Start seeds indoors early or direct sow in the garden after danger of late spring freezes has passed. Insect pollinators are strongly attracted to the flowers and gold finches find the fruit irresistible.
