Deam's black-eyed susan Interesting Notes

Rudbeckia fulgida var. deamii is a fantastic pollinator plant with large, orangish yellow daisy flowers with slender petals and raised dark brown center cones. Growing up to 3' tall and 2' across, this black-eyed susan separates itself from its commonly found cousin, fulgida var fulgida by its clumping habit and hirsute foliage. It freely self-sows when the seed heads aren't picked clean by goldfinches and is a great and easy-going plant for the garden. 

Rudbeckia fulgida var. deamii Growing and Maintenance Tips

Prefers full sun to part sun and can tolerate a wide range of soil conditions from sand to loam to clay. Prefers moderately fertile soil with average soil moisture but can take periods of drought once established. Generally, disease and pest resistant and less likely to get powdery mildew than other Rudbeckia species.
