Xeric Groundcovers Display and Test Garden

This garden tests and demonstrates water-wise groundcover plants that could be used to replace areas of turf, be used to fill in around larger perennials, shrubs or trees and to create edgings along streets and walks. They can function as mulch, reducing evaporation and heating of the soil. Some spread only a little; others spread up to 4’ from one plant. It is not advisable to use only one variety to cover an entire yard; that would create a monoculture, like a lawn, with similar pest and disease problems. Unlike a lawn, these plants will flower, sometimes have fall color and sometimes have evergreen foliage.
