What is lithophytic?

Lithophytic plants are species that grow on rocks or other hard substrates, often in habitats where soil is scarce. These plants are adapted to growing without soil, by attaching their roots to the surface of the rock or directly into cracks and crevices. They are found in a wide variety of environments, from deserts and rocky shores to high mountain regions.

Lithophytes have evolved various mechanisms to cope with the harsh conditions of their habitat. They are typically drought tolerant, and may have small, succulent leaves to reduce water loss. Some species have specialized root structures, such as velamen roots, which can absorb and store water and nutrients.

Lithophytic plants can be used in landscape design, particularly in areas where soil erosion is a problem. They are also popular in terrariums and other indoor gardens, where they can be grown in artificial environments that simulate their natural habitat. However, because they require specialized growing conditions, lithophytes can be challenging to cultivate.
