This species has been cultivated in Britain since at least 1728. It was first recorded in the wild in 1848 at Par (E. Cornwall) and Hayle (W. Cornwall), where it was formerly considered to be native. There are no published records of it at Hayle after 1909, and it was last seen at Par in 1987. It is now a rare casual.
Native of S.W. Europe, extending east to N. Italy.
