A perennial herb with a woody base, naturalised in a few localities such as a sandy beach in E. Kent and by the River Tweed (Roxburghs.). Elsewhere, it is a casual on arable and waste ground, arising from wool shoddy. Lowland.
S. inaequidens was first recorded in the wild in 1836 (Fife). Older records originate from wool shoddy, but it may have arrived in E. Kent (in 1978) as a natural extension of its alien range in France, and it may be spreading in S.E. England.
Native of S. Africa; widely naturalised in Europe.
