Crownvetch blooms as Pennsylvania highways’ erosion ally
Crownvetch or Penngift Crownvetch has become Pennsylvania’s highway staple. Discovered by Dr. Fred Gray near Virginville in 1935, it thrives on poor soils, controls erosion, and requires little care. Today over 30,000 acres line highways and it sees use beyond state borders.
