Up for bid are seeds of Tithonia diversifolia. It is an unusual perennial that gets great green foliage and bright yellow sunflower-like flowers on top of stems to 15 feet tall or more. These unique plants are hardy to USDA zone 8, possibly colder, and they grow best in full sun to part shade. They would make excellent additions to your rare plant collection, or just make a unique statement in your yard.
