Helianthus annus Moulin Rouge is the darkest maroon-black sunflower that we have seen. The flowers are about 6 inches across and are darkest around the black centers. The plants are multi-branching and produce lots of blooms for cutting. Flowers left on the plant turn into natural bird feeders : the flowers go to seed heads and the strong stems serve well as perches. Most/full sun. 5-6 feet. 20+ seeds/pack.
