Cynoglossum germanicum, Green Hound’s-tongue
Cynoglossum germanicum has two sites in Oxfordshire, one near Pyrton and one at Stratford Bridge. The Pyrton site continues to do very well but the Stratford Bridge site has suffered so badly from Goosegrass (Galium aparine) infestation that we have abandoned it.
The population of Green Hound’s-tongue at Pyrton continued to thrive with well over 1500 flowering plants in 2019. There is also an outlying population further up the road with at least 190 adult plants. Goose-grass may also turn out to be a problem at this site.
In 2014, seed was sown in a small area at Aston Rowant NNR. The area was approximately 5 metres square. Since then, the site has been monitored, competition has been removed when necessary and some seeds have been spread by hand every year. The species has also been introduced, with permission, to several new potentially suitable areas of woodland across the Aston Rowant NNR between 2018 and 2020.
