Rudbeckia hirta 'Denver Daisy', a Black-Eyed Susan variety, will cause a commotion in the pollinator garden with her brown eyes and yellow petals craving attention. Her height of 18-28 inches makes her perfect for containers as the main attraction. She'll also display well near the front of the garden bed, so reach for a handful of blooms now and then. Her warmth draws the eye into the garden and makes a lovely addition to your fall decor. Add a pumpkin to her display, and you're ready for the cooler season.
