The 10 Best Drought Tolerant Plants that Grow in Lack of Water

Drought tolerance may refer to which a plant is adapted to arid or drought conditions. These drought tolerant plants make use of carbon fixation to capture more energy in plants during photosynthesis process. It is also good for arid conditions as carbon dioxide at night times allowing stomata to stay close during the daytime and reduces water loss. Desiccation tolerance is the extreme degree of drought tolerance. Another species called xerophytes have adapted to survive in the little liquid environment especially in arctic regions.

For the plant to survive in dry conditions it should have the following…

  • Adaptation of stomata to reduce water loss.
  • Adaptation of root system to increase water absorption.
  • Water storage capacity in succulent plants i.e. above ground parts.
  • Trichomes are the small hairs on leaves to absorb atmospheric water.

All of these plants require water to thrive. However, some plants require more and some require less water to grow in different climatic conditions. Here are the 10 best drought tolerant plants that store water in roots, stems, and leaves and use them for better growth.
