In agriculture, a living mulch is a cover crop interplanted or undersown with a main crop, and intended to serve the purposes of a mulch, such as weed suppression and regulation of soil temperature. Living mulches grow for a long time with the main crops, whereas cover crops are incorporated into the soil or killed with herbicides.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".

Mimosa strigillosa, also known as sunshine mimosa and powderpuff, is a perennial ground cover in the family Fabaceae that is native to nearly all US states bordering the Gulf of Mexico and grows north into Georgia and Arkansas as well. [1] The name powderpuff refers to the small spherical flowers that rise above the plant's creeping vines.
A plant that produces root sprouts or runners is described as surculose. [1] Water sprouts produced by adventitious buds may occur on the above-ground stem, branches or both of trees and shrubs. Suckers are shoots arising underground from the roots some distance from the base of a tree or shrub.
Groundcover of Vinca major. Groundcover or ground cover is any plant that grows low over an area of ground, which protects the topsoil from erosion and drought.In a terrestrial ecosystem, the ground cover forms the layer of vegetation below the shrub layer known as the herbaceous layer, and provides habitats and concealments for (especially fossorial) terrestrial fauna.
Herbicides are often used in these cleaning operations because the correct chemical at the correct dose (e.g. glyphosate or triclopyr) and time will kill only broad leaved species, leaving the conifers unharmed and free to grow. Chemical treatments may be applied by foliage sprays, mists or pellets.
The roots grow into the medium and after a period of time, the stem is separated from the original plant. [1] Tourniquet air layering has a similar method to air layering, except that instead of creating a wound, a wire is wrapped around the stem and the ends are twisted until it is very tight.
The tubers form close to the soil surface and sometimes even on top of the ground. When potatoes are cultivated, the tubers are cut into pieces and planted much deeper into the soil. Planting the pieces deeper creates more area for the plants to generate the tubers and their size increases. The pieces sprout shoots that grow to the surface.
