Xeriscaping involves not only plant selection but also grouping plants according to wster needs. If plants are grouped properly, supplemental irrigation can be applied only to the plants that need it. To help with grouping, this listing of plonts includes water-use zones for eoch plant. The water-use zones are divided into three cotegories - (1) regulor irrigation; (2) moderate, occassional irrigation; and (3) low, no irrigation. This information is based on observation, experience, and several cross references from notable horticultural sources. Many plants can grow in any or all of the three zones. For greatest wster conservation, use plants in zones that require the least amount of water.
The condition of the planting site should match the water-use zone. Place plants that require more water in areas of the landscape that stay moist and plants that need less in areas that are naturally drier.
Hardiness zones refer to regions of North Carolina that are suitable for the plant. The map on this page indicates the zones.
It is surprising to learn how many plants can thrive without supplemental water once they are established. The following pages list plants that are easily grown and readily available to North Carolina home gardeners and landscapers. The information given for each plant will help you make plant selections thst create an attractive and water-efficient landscape.
