Trifolium hirtum is a species of clover known by the common name rose clover.^[1]^[2] It is native to Europe, Western Asia, and North Africa. It is present elsewhere as an introduced species and it is cultivated as a cover crop and animal fodder. It was introduced to California from Turkey in the 1940s as a forage crop, and today it is a widespread roadside weed there.^[3]^[4]

It is a hairy annual herb growing erect in form. The leaves have oval leaflets up to 2.5 centimeters long and bristle-tipped stipules. The inflorescence is a head of flowers about 1.5 centimeters wide. Each flower has a calyx of sepals with long, needlelike lobes that may harden into bristles with age. The calyces are coated in long hairs. The flower has a pink corolla 1 or 1.5 centimeters long.
