Sawtooth Sunflower
Helianthus grosseserratus
Sawtooth sunflower is a tall, perennial member of the sunflower family that is common in open grasslands and nutrient rich soils. All classes of livestock readily consume this species. Sawtooth sunflower blooms in late summer and is easily recognizable by its bright yellow flowers held high upon these tall plants. This plant can spread by rhizomes, which allows it to fill in areas that it finds favorable. Consider higher planting rates in pastures to provide forage while maintaining pollinator friendly plants and blooms. In home gardens this plant can be aggressive. Consider planting at the back of garden beds.
