Grass varieties for roadsides1

Stemminess appears to be a major problem with grasses used along roadsides, particularly with increasing unmowed acreage. The 56-chromosome spreading fescues (Festuca rubra L. subsp. rubra) appear promising in reducing this problem. In the seedling stage these grasses exhibit sufficient vigor, manifest a rich green foliage throughout most of the season, retain their color during drought, produce a dense canopy that excludes weeds, are rhizomatous and fill voids quickly, are good seed producers when managed for seed production, and produce a minimum of seedstalks when unmowed. The “common” types of Kentucky bluegrass (Poa pratensis L.) have long foliage, produce moderate numbers of seedstalks which lodge readily, persist under low fertility better than good turf-types, and appear compatible with either spreading or creeping fescues. Short-leaved Kentucky bluegrass varieties and the Chewings fescues require more intensive mowing, fertilization and irrigation to maintain acceptable appearances. At least one hard fescue variety maintained good color under minimum maintenance, but its compatibility with long-leaved grasses is doubtful. Disease was a serious factor under roadside conditions only with ryegrass. All perennial ryegrasses tested proved susceptible to anthracnose (Colletotricum graminicolum (Ces.) (Wils.)). Smothering when unmowed was serious with certain fine fescues, but not with Kentucky bluegrass varieties.
