Drought-Tolerant Shrubs
Drought-tolerant shrubs are shrubs that can withstand dry weather once established. No landscape plant is drought-resistant until it becomes established in the site.
Once a drought-tolerant shrub is established and has a deep root system, it requires less water. All plants require a steady supply of moisture when first planted.
Most shrubs require a year or more to set down deep roots. In the first couple of years after planting do not neglect watering drought-resistant shrubs.
Shrubs listed here will survive several months without water once established. Many will survive on rainfall and need no additional irrigation.
