👉 Visania is a type of plant that grows on rocks or other hard surfaces, often in association with other plants. It has a unique appearance due to its underground roots and leaves, which are typically green but can also be white or gray. The plant's leaves are sessile (not attached to the ground), with long, narrow blades. Visania is known for its ability to grow on rocks without soil, providing shelter for various animals such as insects, fungi, and even some plants.
