About Orange Coneflower, Rudbeckia Seed
Orange Coneflower (Rudbeckia fulgida var. sullivantii) is a native perennial with golden-orange flowers and a compact, mounding habit. Plants reach about 3 feet and bloom from midsummer into early fall in full sun or partial shade. The flowers attract bees, butterflies, and other beneficial insects, and the mature seed heads provide food for birds. Seed requires 60 days of cold, moist stratification and should be surface sown.

Pests & Diseases
Leaf spots and powdery mildew can occur when foliage remains wet or plants are crowded. Provide adequate spacing and airflow, water near the soil surface, and remove heavily affected plant debris. Avoid overhead watering late in the day.
Young plants may be damaged by slugs, snails, aphids, or other chewing and sap-feeding insects. Healthy established plants generally tolerate light feeding. Identify the pest before treatment and use the least disruptive control to protect visiting pollinators.
