Saxicolous plants are those that grow on rocks or rocky surfaces. These plants have adapted to thrive in harsh conditions, where soil is limited and moisture can be scarce. They often have specialized structures, such as deep roots or thick leaves, to help them retain water and nutrients. Common examples of saxicolous plants include certain types of mosses, lichens, and alpine flowers. These plants play a crucial role in their ecosystems by preventing soil erosion and providing habitats for various organisms. Their unique adaptations allow them to survive in environments where other plants may struggle.
