A climbing or scrambling perennial herb which is grown in gardens and is naturalised as a relic of cultivation on sand dunes at Burnham Overy Staithe (W. Norfolk). It also occurs beside a flooded gravel pit at Yateley (N. Hants.). Lowland.
L. heterophyllus was introduced into cultivation in Europe in 1731. It survives in Norfolk from a garden created in the 1940s, and was recorded from Hampshire in 1987. The plant on a railway bank at Kingsley (N. Hants.) mentioned by Clement & Foster (1994) has now been redetermined as L. sylvestris (Brewis et al., 1996).
Native of S.W. Europe; the species is closely related to L. latifolius.
