Drought-tolerant plants are those that have adapted to survive and thrive in environments with limited water availability. These plants have developed various mechanisms and characteristics that enable them to endure long periods without rain or irrigation. Understanding these traits is crucial when selecting plants for a drought-tolerant garden.

The key features that make a plant drought-tolerant include:

• Efficient water use: Drought-tolerant plants can store water in their tissues or reduce water loss, making them efficient at using available moisture.
• Deep root systems: Many drought-tolerant plants have deep or extensive root systems that enable them to access water from deeper soil layers, which is especially beneficial during dry spells.
• Leaf adaptations: These plants often have waxy or hairy coatings on their leaves, reducing water loss through transpiration. Some may have small or needle-like leaves to minimize the surface area exposed to the sun.
• Water storage: Some plants can store water in specialized tissues, such as succulents that store moisture in their fleshy leaves or stems, allowing them to survive dry conditions.

Water conservation is at the heart of drought-tolerant plants' survival strategies. These plants are highly adapted to retain and efficiently use water, making them ideal for regions with low rainfall or irregular water supply.

In addition to the traits listed above, many drought-tolerant plants have evolved to cope with extreme environmental conditions. These plants can:

• Reduce the transpiration process (water loss through leaves) by closing their stomata during hot weather.
• Perform photosynthesis during cooler parts of the day or night when water loss is minimized.
• Use CAM (Crassulacean Acid Metabolism) photosynthesis, a special form of photosynthesis used by succulents, where stomata remain closed during the day and open at night.

It’s essential to differentiate between native and non-native drought-tolerant plants. While both types can survive with minimal water, native plants are generally better suited to the local climate and soil conditions. Native plants have evolved over thousands of years to adapt to the specific weather patterns and environmental challenges of a region. They are more resilient to local pests, diseases, and temperature fluctuations, making them a sustainable choice for drought-tolerant gardens.

On the other hand, non-native drought-tolerant plants may require more care and attention to thrive in local conditions. They might need special soil amendments, extra irrigation during establishment, or more frequent maintenance to ensure they continue to thrive in unfamiliar environments.

Overall, native drought-tolerant plants are the best option for low-water gardens as they are naturally adapted to survive in challenging conditions and require less ongoing maintenance.
