Drought tolerance is an important consideration for landscape plants. If a plant is not drought tolerant, it will need to be watered more frequently and may not survive in areas where rainfall is scarce.
Some signs that a plant is drought tolerant:
- The plant has deep root systems that can reach down to find water.
- The plant has thick leaves or waxy coating on the leaves.
- The plant blooms late in the season so it doesn't need as much water early on.
- The leaf size of the plant is small, which means less transpiration (water loss).
