Autumn Colors

Black-eyed Susan

70d to harvest

Velvety petals unfurl in a warm autumn palette—golden ochre to burnished amber—each bloom anchored by a deep, inky black eye that seems to glow at dusk. “Autumn Colors” forms a sturdy, upright clump of richly textured foliage and produces abundant, daisy-like flowers with a crisp, satiny sheen that holds its presence in the garden for weeks. Grow it for long-lasting color in beds and borders, and enjoy its effortless, pollinator-friendly charm as it settles into a late-season show.

Frequently Asked Questions

What should I do if my Autumn Colors plants get powdery mildew on the leaves?

Powdery mildew shows up as a gray-white coating on leaf surfaces, usually during warm days with cooler nights. Remove the most affected leaves right away, water at the base in the morning, and space plants to improve airflow. If it keeps spreading, spray with a sulfur-based fungicide and repeat according to the label after 5–7 days as needed.

How can I tell when Autumn Colors is ready to harvest at about 70 days?

Harvest when the foliage has reached its peak “autumn” coloration and leaves feel fully formed, not limp or newly emerging. For best quality, don’t wait for widespread browning—pick when color is bold across most plants. If you’re harvesting stems or bunches, cut early in the day when leaves are crisp to reduce wilting.
