Leaf size: approximately 6 inches.

Rudbeckia fulgida requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Orange Coneflower thrives in full sun light conditions. The optimal light range is 2000–5000 lux. Avoid placing Orange Coneflower in direct, harsh sunlight for extended periods, as this can scorch the foliage.
