• Abstract:
  The objective of this research was to develop new recommendations for establishing 29 native grass and forb species for roadside vegetation in Georgia. Blackeyed Susan (Rudbeckia hirta L.), swamp milkweed (Asclepias incarnata L.) and indiangrass (Sorghastrum nutans (L.) Nash) were the quickest to establish of all species, while blackeyed Susan, lanceleaf coreopsis (Coreopsis lanceolata L.) and wild bergamot (Monarda fistulosa L.) provided the greatest ground cover over the 12 month experiment. At four of the five sites, an additional 1 to 4 more of the species evaluated established ≥20% ground cover in the spring seeding compared to fall. Species seeded in the spring also established faster during the first four months after seeding. Overall, blackeyed Susan, indiangrass, lanceleaf coreopsis, swamp milkweed, and wild bergamot have the best potential, of the species tested, to establish under roadside conditions in Georgia.
