Sawtooth Sunflower is a tall, stately perennial that can grow 6 to 10 feet in height, adding vertical drama to any landscape. Its bright yellow, sunflower-like blooms appear in late summer to early fall, drawing in bees, butterflies, and other pollinators. The plant’s serrated leaves, which inspired its name, add additional texture and interest.

Sawtooth Sunflower prefers full sun and moist to moderately dry soils. It is adaptable to various soil types, including clay, and thrives in prairies, ditches, and meadows. Its robust growth makes it excellent for erosion control along slopes and waterways. It also naturalizes easily, making it a practical choice for large-scale restoration plantings.

Ecologically, the Sawtooth Sunflower is a powerhouse. It provides abundant nectar and pollen for pollinators and seeds for birds in the fall. Its tall, dense growth also offers cover and habitat for small wildlife, supporting healthy ecosystems. This makes Helianthus grosseserratus a perfect choice for gardeners and conservationists who are inspired to create diverse, pollinator-friendly landscapes with bold, seasonal displays.
