Wildlife Significance Brown-Eyed Susan

Host Plants – Rudbeckia family are host plants for dozens of butterfly caterpillars including: pearl crescent, silvery checkerspot and wavy- lined emerald.
Nectar Plant –Plants in this family provide a wonderful nectar source for: bees, butterflies, moths, skippers and numerous other insects. Deer - Are not fond of this plant
If we strive to increase the insect population through the addition of native plants we will in turn create a “Mc Donald’s” effect for birds and their young. Our backyards, regardless of size, connected with our neighbors will begin to provide a landscape that is once again teeming with life.
