15 Miraculous Drought Tolerant Plants That Hardly Need Any Water To Survive
Naturally, all flora requires water to survive. However, some hardly need consistent availability of water to survive thereby qualifying them the name: drought tolerant plants. They are the category of plants that can survive without water for months or even years of scarce rainfall due to their adaptation. With the variations in weather patterns and conditions across different terrestrial regions, plants in drought areas have adapted to survive the harsh climatic conditions of thriving without water.
Climate change and global warming have further made the plants much more tolerant by developing survival mechanisms for enduring dry conditions. Most of these plants can survive in areas with less than 25.4 centimeters (10 inches) of rain per year.
As evident from the survival tactics of the majority of drought-tolerant plants, some have developed thick leaves while some have very thin and need-like leaves to store water and reduce the rate of water loss respectively.
The majority of drought-tolerant plants also have deep roots that extend to great depths to reach the water. To get to know exactly the nature of these kinds of plants, here are the top 15 on the list of drought-tolerant plants.
