Range & Status
Endemic to south-west England and Ireland.
Scattered throughout Cornwall, mainly within 5km of the coast. There are concentrations on The Lizard, Penhale (SW75), Newquay (SW86), the Roseland Peninsula (SW83) and the Port Isaac area (SW98). On the Isles of Scilly it is common on the inhabited islands and may persist on Te\'e4n (SV91).
Habitat & Ecology
It occurs on roadside banks, hedges, cliff-tops, disused railways, stream-sides, ruined settlements and historic field sites, also in waste places and sandy areas. On Scilly it is also found in bulb-fields.
Few known threats, possibly only the destruction of hedges and uprooting by Man.
Very few sites are protected.
