Produces showy pyramidal sprays of golden yellow flowers from August into October.
Provides crucial late-season food source for pollinators (native bees, butterflies, and syrphid flies). Attracts beneficial predatory insects like predator wasps and beetles.
Prefers well-drained poor soil. Spreads vigorously from rhizomes as well as by seed, and can be planted in masses in a wildflower meadow. Spread can be controlled by planting in a submerged pot.
