However, we have found this plant acts more like an annual, leaving little seedlings all over the garden Over the Years - This lovely lady adds a splash of delicate beauty into any wildflower garden. Oh, but don't be deceived by her seemingly gentle nature. One or two plants quickly feels like a family reunion. Note, we no loner raise this Rudbeckia for our markets

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
Diversity - If we strive to increase the insect population through the addition of native plants we will create an environment conducive for birds to thrive and raise their young. Our backyards, regardless of size, connected with our neighbors will begin to provide a landscape that is once again teeming with life.
