This clover with a Mediterranean distribution is present (in the wild or as a weed escaped from cultivation) in all regions of Italy, except perhaps in Valle d'Aosta. It is sometimes cultivated as a forage crop on decalcified, sub-acid, fresh clay soils, from sea level to the subalpine belt. The species is rare in the outer belt of the Sardinian temporary ponds, in contact with forage crops. The genus name derives from the Latin word 'tri' (three) and 'folium' (leaf), referring to the leaves, that are divided into 3 leaflets; the species name refers to the flesh colour of the flowers. Flowering period: April to June.
