Nepenthes sp. Misool growing as a lithophyte in Raja Ampat, New Guinea. Lithophytes are plants that grow in or on rocks.They can be classified as either epilithic (or epipetric) or endolithic; epilithic lithophytes grow on the surfaces of rocks, while endolithic lithophytes grow in the crevices of rocks (and are also referred to as chasmophytes).

One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...
Plug plants are very useful if the sowing window is missed, and plugs can be purchased quickly to replace a crop which has failed. As a garden develops, interplanting (intercropping) existing crops with plugs plants, ideally companion plants, can improve the productivity of the space and so maximise harvests – a sown crop may not be able to ...
The Japanese rock garden, or dry garden, often referred to as a "Zen garden", is a special kind of rock garden with a few large rocks, and gravel over most of the surface, often raked in patterns, and no or very few plants. Other Chinese and Japanese gardens use rocks, singly or in groups, with more plants, and often set in grass, or next to ...
Composite patterns: aphids and newly born young in arraylike clusters on sycamore leaf, divided into polygons by veins, which are avoided by the young aphids Living things like orchids, hummingbirds, and the peacock's tail have abstract designs with a beauty of form, pattern and colour that artists struggle to match.

Growth from any such meristem at the tip of a root or shoot is termed primary growth and results in the lengthening of that root or shoot. Secondary growth results in widening of a root or shoot from divisions of cells in a cambium. [8] In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual ...
Lithophyte – Growing on rocks Endolithic – growing in crevices of rocks. Epilithic – growing on the surface of rocks. Mallee – a term applied to certain Australian species which grow with multiple stems springing from an underground lignotuber. Parasitic – using another plant as a source of nourishment.
This process results in roughly spherical concretions that grow with time. In the case of pervasive growth, cementation of the host sediments, by infilling of its pore space by precipitated minerals, occurs simultaneously throughout the volume of the area, which in time becomes a concretion. Concretions are often exposed at the surface by ...
