White clover (Trifolium repens) is a species of clover native to Europe, North Africa, and West Asia. It has been widely introduced worldwide as a pasture crop, and is now also common in most grassy areas of North America and New Zealand.

It is a herbaceous perennial plant. It is low growing, with heads of whitish flowers, often with a tinge of pink or cream that may come on with the aging of the plant. The heads are generally 1.5-2 cm wide, and are at the end of 7 cm peduncles or flower stalks . The leaves, which by themselves form the symbol known as shamrock, are trifoliolate, smooth, elliptic to egg-shaped and long-petioled. The stems function as stolons, so white clover often forms mats with the stems creeping as much as 18 cm a year, and rooting at the nodes .

White clover grows among turfgrass, crops, and in a large number of other landscapes. It is also found in a limited range of different field type environments. White clover can tolerate close mowing, and can grow on many different types and pHs of soil, but prefers clay. It is considered to be a beneficial component of natural or organic lawn care due to its ability to fix nitrogen and out compete lawn weeds. Natural nitrogen fixing reduces leaching from the soil and can reduce the incidence of some lawn diseases that are enhanced by the availability of synthetic fertilizer.
