Drought Resistant Trees, Shrubs and Perennials

Choose heat-loving, drought resistant trees and shrubs for a xeriscape garden but do not forget that even these plants will need at least weekly watering while they get established during the first growing season.

Examples of trees and shrubs, which survive in hot dry areas of the garden, include :

  • Cherry Prinsepia
  • Golden Flowering Currant
  • Genista
  • Hackberry
  • Honeysuckle
  • Juniper
  • Potentilla
  • Sea Buckthorn
  • Sumac - Gro-Low ground cover
  • Ash
  • Buffaloberry
  • Pine
  • Pincherry

The following perennials, once they are firmly established in the garden, are heat and drought tolerant. They will still need to be watered in extremely hot weather but not as often as other less drought resistant plants, which need regular watering throughout the growing season.

  • Potentilla – Red, orange or yellow blooms shrub also available in heights suitable for ground cover.
