As part of a cooperative project between Pennsylvania State University and the Pennsylvania Department of Transportation, a study was initiated to investigate the performance of 50 different wildflower species for use on Pennsylvania's roadsides. Each species was evaluated for percent cover, percent weed invasion, and percent of the plot covered by blooms. The wildflowers were planted in the spring of 1988; their performance is evaluated through 1989.
