Drought tolerant gardening is the process of landscaping or gardening that reduces or eliminates the need for supplemental water from irrigation. It is promoted in regions that do not have accessible, plentiful, or reliable supplies of fresh water and is gaining acceptance in other regions as access to irrigation water is becoming limited. Plants whose natural requirements are appropriate to the local climate are emphasised, and care is taken to avoid losing water to evaporation and run off. The specific plants used in drought tolerant gardening depend upon the climate. Drought tolerant landscaping is different from natural landscaping because the emphasis is on selection of plants for water conservation, not necessarily selecting native plants. With recreation time at a premium, and a growing global concern for the supply of water, savvy gardeners and designers are adopting drought tolerant principles into every part of their landscape design. Until recently, drought tolerant plants and designs have most commonly been a feature around commercial sites, roundabouts and traffic islands. As water conservation awareness grows, drought tolerant landscape design is catching on – particularly in regions like Central Otago, Canterbury and wind windswept coastal areas of New Zealand. The trick to drought tolerance is choosing a landscape designer who can select plant species that are appropriate for your climate. Natives are an obvious choice, as they naturally grow in the local conditions, however, introducing exotic species into the design can achieve stunning looking gardens. A mix of native and exotic species will provide great contrast of colours and textures creating a more visually attractive design with more seasonal interest.
