Regional plants are species of flora that are native to specific geographic areas. These plants have adapted to the local climate, soil, and environmental conditions, making them well-suited for their habitats. Examples include cacti in arid regions and mangroves in coastal areas. Understanding regional plants is important for biodiversity and ecosystem health. They provide food and shelter for local wildlife and can help maintain soil stability. Additionally, using native plants in landscaping can reduce water usage and support local ecosystems, making them a sustainable choice for gardens and parks.
