Plant Profile: Rudbeckia maxima

Rudbeckia maxima, commonly known as the Large Coneflower, is a robust herbaceous perennial belonging to the daisy family. This plant thrives in average, moist, well-drained soils and flourishes in full sunlight. It is a resilient species that can tolerate light shade, high temperatures, occasional drought, nighttime visits from deer, and a variety of soil types. While it can be cultivated from seeds, it often self-seeds under optimal conditions and also spreads through rhizomes. This makes it an excellent choice for borders, cutting gardens, pollinator gardens, cottage gardens, or naturalized areas.

The flower stalks can reach heights of up to 7 feet, showcasing vibrant yellow flowers with drooping rays and a dark brown central cone measuring between 2 to 6 inches. Once the flowers have seeded, they attract various songbirds, including goldfinches.

In terms of pests and diseases, this plant is relatively low-maintenance. However, young plants may be susceptible to damage from snails and slugs. Powdery mildew can occasionally occur, but healthy specimens typically bounce back without issue.
