UK Status

Becoming well established in Britain. Stace (1997) described it as naturalised in one site in Kent and accurately predicted that it would soon spread. Although still concentrated in southern England, this plant is now found here and there all over England, north Wales and even in one or two places in Scotland

VC55 Status

Rare in Leicestershire and Rutland but possibly increasing in our area. It was not recorded in the 1979 Flora survey of Leicestershire. There were only three records for this species in Leicestershire up to 2010.  In the current checklist (Jeeves 2011) it is listed as Alien; casual
