ESTABLISHMENT OF GROUND COVERS FOR NON-MOWABLE AND LOCKED-IN AREAS OF LOUISIANA INTERSTATE HIGHWAYS--PHASE I REPORT

Card files were made for about 200 different plants which had possibilities for use as low-growing groundcovers for use along highways in Louisiana for unmowable areas. Literature references include over 150 for which cards were made. Selective references, especially helpful, are listed. Propagation studies include 75 different plant materials. In 50% shade, Lysimachia nummularia, Ajuga reptans 'atropurpurea' and Duchesnea indica were best. All are readily propagated and aggressive and have aesthetic value. Achillea millefolium, Sedum sp., Rosa wichuriana and Portulaca sp. were good. Closer spacing was indicated for some with rosette-type growth. Problems were encountered in a trial highway planting by pilfering, traffic and drought. Plants readily propagated included Bronze Wintercreeper, Climbing Fig, Turkey Ivy, Algerian Ivy, Skogsholmen Contoneaster, Plumbago, Stoncrop, Memorial Rose, Periwinkle, Lantana, Verbena, Purple Heart Plant, Wandering Jew, Baby Wintercreeper, Moss Rose, Lemon Balm, Halls Honeysuckle and Bronox Forsythia.
