white clover, Weiß-Klee

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.
