stabilize soils, and reduce erosion. Plus, they are a beautiful sight! The wildflower mix used in this study was comprised of various wildflowers native to North Carolina.
Wildflowers are an alternative to traditional turf grass for vegetation cover along roadsides. Two coneflower variations of the Aster family are shown: the yellow flowers are Rudbeckia hirta (Black-eyed Susan)and the purple flowers are Echinacea purpurea (Purple Coneflower).
Experimental plots were established along highways to test soils with turf grass and with wildflower cover. Experimental plots were tilled before seeds were planted.
