Rudbeckia subtomentosa
Sweet Coneflower is a herbaceous perennial in the Asteraceae family. This coneflower likes full
sun to part shade, and would love to shine in a cottage garden or cut flower garden. Bright
yellow petals surround brown disks in summer and fall, then birds enjoy the seeds after the
flowers are gone. Sweet Coneflower is drought resistant, making it a good candidate for the dry
spots in your garden.
