Growing a drought-tolerant garden is a great way to conserve water and spend less time watering and more time enjoying your garden. Drought-tolerant plants are ones that, once established, can handle some dry spells. The best drought-tolerant plants are ones that add beauty to your garden and often, serve other purposes, like attracting pollinators or providing screening. When buying drought-tolerant trees, shrubs and bushes, perennials, ground covers, flower bulbs and more for sale online, make sure the plants are suitable for your grow zone. Other factors to consider include light requirements (full sun, partial shade or full shade), soil requirements, the plant's mature height and spread, harvest or flowering time, and other qualities, including your own personal preference.
