These plants are highly recommended for our drought conditions and highly resistant to most insects and diseases.

Perennial: Plant that lives longer than two years and has little or no woody growth. Unless otherwise noted, perennials listed here are hardy in Parker County, thriving in our soil and in our climate conditions.

  • Tender Perennial: Plant that is able to survive mild winters, but may not survive a severe winter.
  • Heat Sensitive: Plant that may suffer when the temperature soars in July and August.
  • Deciduous: Plants that will die back in autumn or winter and return again in spring. Plants that return from the root may be pruned to the ground in early spring. Plants that return from the stem should be pruned sparingly to control the shape or size.
  • Low Water Requirement: Plants that can survive on rainfall alone, once established. These are our hardiest plants, and watering them too much may actually harm the plant. In general, these plants can survive on rainfall alone; and during drought with no more than one inch of rain every 30 days. When rainfall is absent for an extended period of time, or when it is absent during the hottest days of summer, these plants will benefit from supplemental water.
  • Drought Tolerant: These plants will perform best with one inch of water once a week (including rain). Once established, these plants are able to survive drought conditions when watering is temporarily restricted.
