Sweet Black-Eyed Susan
Rudbeckia subtomentosa
Sweet Black-Eyed Susan (or sometimes simply Sweet Coneflower) bears buttery, deep yellow petals that radiate from rich chocolate-brown central cones. The flowers bloom profusely from late summer to early fall, providing a vivid splash of color when many other perennials are fading. The plant's leaves emit a subtle sweet fragrance, adding another layer of sensory appeal. This coneflower thrives in full sun and well-drained soil, making it an excellent choice for borders, wildflower meadows, and pollinator gardens. It’s a resilient and low-maintenance plant, capable of withstanding drought once established.

Maintenance Tips
- Drought-tolerant once established; water regularly until then, especially in hot, dry periods.
- Deadhead to encourage more blooms and prevent excessive self-seeding.
- Divide every 3-4 years in spring or fall to rejuvenate clumps and spread the plant in the garden.
- Allow seedlings to establish if additional plants are desired or remove them to keep the planting area neat.
