Here is a news report on North Carolina's wonderful wildflower program. It shows gorgeous, innovative roadside plantings. You can help Florida surpass North Carolina's program by contacting the Florida Department of Transportation. Its wildflower program is consumer-driven, and you can keep it going strong by asking that wildflowers be planted along roadsides in your area.
Contact Jeff Caster, head of the FDOT wildflower program, to ask for more roadside wildflowers: Jeff.Caster@dot.state.fl.us.
