Trifolium hybridum (Alsike Clover)
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).
T. hybridum used to be much grown as a forage crop and was recorded from the wild by 1762. It is still grown on a small scale as a green manure. It was mapped as `all records` in the 1962 Atlas, and its distribution is stable.
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.
