Sawtooth Sunflower does very well in full sun and moist soil with high organic matter . This sunflower stands out to other sunflowers by its reddish-purple stem, surprising its leaves are only slightly serrated despite its name. This sunflower has very attractive foliage by growing to large heights and at the upper half branching can occur creating more flowering stems, and the flowers grow in small clusters at the top of the plant as well. Sawtooth Sunflower grows up to 12 feet, but in dense colonies, it may only reach 5 feet.
