Have you been to a bluebell wood recently?
The stunning sight of the floor of a greenwood, turned blue is a wonder enjoyed by many.
However, all may not be as tranquil as it looks in the forest. The native bluebell in Britain (Hyacynthoids non-scripta) is giving ground to its larger cousin, the Spanish Bluebell (Hyacythoids hispanica)
Spanish bluebells are larger and lighter coloured than the native bluebell. The two species cross-breed, threatening to change the shape and colour of bluebells across the country.
(Both native and Spanish species can have occasional white flowers but only the Spanish bluebell can have pink flowers. )
