Native plants water less. They thrive in their native climate, rainfall, and soil. Many non-native plants require watering. Lisha Astorga, proprietor of Desert Straw House in Palm Springs, California.
Native plants need less water.
Native plants have extensive root networks that can reach soil water, therefore most can endure periods of little to no precipitation. Large root systems let plants endure droughts by tapping subsurface water supplies.
Some are drought-tolerant.
Because of their local adaptations, native plants seldom require fertilizer. Plants that need plenty of nutrients must be fertilized, particularly in poor soil, yet many native plants have adapted to it.
They need less (or no) fertilizer.
Native plants require insecticides less than non-natives. Reduced chemical use improves the environment because pesticides and herbicides damage soil and water, affecting wildlife that needs food and water.
Native plants need fewer pesticides.
Native plants' deep root systems help them endure droughts by obtaining soil water and increasing soil water storage. By absorbing extra water from heavy rain or irrigation, native plant roots reduce water runoff and soil erosion.
They prevent erosion.
Birds, pollinators, insects, and small animals may find food and shelter in regional natural plants. They feed pollinators and migrating birds. Biodiversity and sustainability depend on native flora.
They provide food and shelter for wildlife.
Many local plants are disease-resistant due to natural selection. Some plants that were susceptible to illnesses in their native environment developed resistance or perished.
Native plants are less susceptible to disease.
Native flowers that attract pollinators are helpful around food crops and with many hybrids. Whether your garden is 100% native or you want to mix native and non-native species, they should thrive if planted properly.
Some make good companions.
