FLOWERING ORNAMENTALS CAN CONTROL ROADSIDE EROSION

FLOWERING AND ORNAMENTAL PLANTS NORMALLY GROWN IN HOME GARDENS AND LANDSCAPES CAN ALSO CONTROL EROSION AND BEAUTIFY HIGHWAY EMBANKMENTS. OVER 35 SPECIES OF ANNUAL AND PERENNIAL PLANTS PROVED EFFECTIVE AND ATTRACTIVE ON PLOTS OF EXPOSED SUBSOIL FROM HIGHWAY CUTS, FILLS, AND DITCHES. ABOUT 2,500 ROADBANK PLOTS OF DIFFERENT SOILS AND EXPOSURES WERE PLANTED. MOST OF THE PLANTS TESTED SHOWED POTENTIAL FOR ROADSIDE EROSION CONTROL AND BEAUTIFICATION. CROWNVETCH IS ONE OF THE MOST PROMISING PLANTS TESTED. HONEYSUCKLE, SERICEA, AND NATIVE BROOMSEDGE GREW WELL NEXT TO WOODLANDS WHERE LACK OF SUNLIGHT LIMITS GROWTH OF MANY PLANTS. DAYLILIES AND IRIS COVERED THE TEST BANK IN 2 YEARS. NATIVE BROOMSEDGE DEVELOPED AN EXCELLENT COVER WITH ONLY A SMALL AMOUNT OF FERTILIZATION. IT ALSO WITHSTOOD DROUGHT WELL. HONEYSUCKLE ADAPTED WELL TO STEEP BANKS.
