Rediscovered in 2009 not far from where it was last recorded in 1948. It was locally frequent

interesting flora typical of more calcareous substrates.

Nationally, this scarce native species has had its range significantly expanded and confused
due to the establishment of numerous populations resulting from garden escapes and throwouts.
In Huntingdonshire, it is similarly difficult to segregate native colonies from those that
are of non-native origin. It has been suggested that flower morphology might be indicative,
with only ‘pin’ flowered plants being native in the East Anglian fens (Stewart et al. 1994).
However, while this might raise doubts about the status of any ‘thrum’ flowered colonies,
