Studies show that there are nearly 450,000 species of plants in the world. Naturally, all plants require water to survive. However, some species can thrive without water for months or even years, qualifying as drought-tolerant plants.
Drought tolerant plants help you reduce water use, especially when rainfall levels are low. In addition, these plants are likely to adapt to the environment, which means you will spend less time pruning, fertilizing, and caring for your plants.
Climate changes have presented gardeners with the challenge of gardening with less water. This makes it important to prioritize the plants with a degree of drought tolerance.
The majority of the drought-tolerant plants boast elaborate adaptation mechanisms, including thick stems and succulent leaves that store more water, glossy, shiny leaves that deflect sunlight, and skinny and needle-like leaves that minimize the rate of water loss.
They also have deeper roots extending to great depths to reach the receding water table. Read on for more information on the nature of these types of plants.
