Arable Weeds at Boscregan Farm

Arable weeds at Boscregan Farm

Boscregan Farm is home to a rare and beautiful wild flower called Purple Viper’s Bugloss which is most commonly seen in Southern and Western Europe, North Africa and beyond. It is very rarely seen in Cornwall, but careful conservation techniques and work with the tenant farmer has encouraged this plant to grow in great numbers. In late June/early July they are out in full bloom, interspersed with yellow corn marigolds.

Purple Viper’s Bugloss has probably grown at Boscregan for centuries, but it was first recorded there in 1873. When the National Trust acquired the land in 1995, the number of plants in each field could be counted individually. Nowadays, it has become impossible to count individual plants and the team have to estimate how many thousands of them are in each field. The National Trust and its tenant farmer have been so successful in saving Boscregan’s rare arable weeds that great swathes of purple and yellow are now visible from as far away as Land’s End during the summer.


On Friday 14 July at 2pm, Simon the area ranger is leading a walk and talk with the tenant farmer at the farm to talk about these special flowers. The event is free to all, meeting at Nanjulian Valley car park and walking down to Boscregan. Sensible footwear is advised, no booking required.
