Trifolium hybridum (Alsike Clover)


Summary Information


An annual of grassy banks, meadows, roadsides and waste places. It is a frequent, often unintentional, constituent of seed mixtures, but rarely persists once a closed sward has developed. Its persistence in some areas probably relies on repeated introductions. 0-350 m at Stainmore (Westmorland).



World Distribution

Native subspecies occur in S. Europe & S.W. Asia, especially in the mountains. Most of our plants are the cultivated subsp. hybridum, which is widely naturalised further north in Europe and elsewhere.
