regrown

Regrown is the past participle form of regrow and is used as an adjective to denote something that has grown again after loss, injury, or pruning. The related noun form is regrowth. The term is commonly applied across biology, botany, and everyday language to describe renewed growth rather than the initial development.

In plants and ecosystems, regrowth refers to the ability of tissues or structures to reemerge after damage or pruning. Many perennials sprout new shoots from existing buds when a stem is cut back, and some grasses or shrubs rapidly regenerate after mowing or grazing. Regrowth also describes the renewal of roots, shoots, or leaves following environmental stress, and it can play a key role in forest and landscape recovery after disturbance.

In animals and humans, regrowth encompasses a spectrum from complete to partial restoration. Some species, such as certain amphibians, can regrow lost limbs; others show organ or tissue regeneration to varying degrees, such as liver regrowth in mammals. Humans typically experience regrowth at slower rates for hair, nails, and some tissues, while scar tissue may form in areas where full regeneration is limited.

In medicine and agriculture, regrowth is a central concept in regenerative therapies, tissue engineering, and crop management. Researchers study signals and mechanisms that promote regrowth to improve healing, while farmers and gardeners manage pruning and cultivation practices to encourage desirable regrowth patterns.
