The wall surrounding the churchyard is notable for its large population of Wall-rue (Asplenium ruta-muraria), perhaps our best location for this county rarity.
Even rarer, and nice to re-find, is the small colony of Rustyback (Asplenium ceterach). Two mature plants were found along with a small more-recently established plant. Currently this species is only known from two locations in Huntingdonshire - Stilton and Model Farm, Old Weston.
However, the best find was left till last. When photographing the ferns I caught a glimpse of red and yellow on the other side of the wall and was surprised to see a Columbine. This is Long-spurred Columbine (Aquilegia x cultorum), a name covering numerous hybrids derived in cultivation from crosses between various Columbine species. In this instance there seems little value in trying to assign the plant to a cultivar given it is self-sown and has probably not come true. A great find to end the day and new to the county.
