Helianthus giganteus, also known as Tall or Giant Sunflower, is a perennial wildflower native to Michigan. It can reach 8 feet tall and flowers from July to September with a yellow blossom two to three inches wide. The long bloom time is one of this sunflower's best features. It prefers full sun to partial shade, medium to wet soil and will grow in clay, loam, or sand.  Giant sunflower is useful for privacy plantings, rain gardens, or naturalizing larger spaces. Also a good choice for difficult clay sites, with sturdy, 9-foot root systems that can loosen tough soil.


Single plants will come in plastic pots (Approx. 4” x 4.5”) Plants will vary in size between 2 and 10 inches.
