This is quite a rare species and I have never seen it. So in a break with tradition I have sought permission from a member of the Wild Flowers of Britain and Ireland. group on Face Book, to use some photos which he took,in order to illustrate this post. The person who has kindly given his permission to use his photos is called Jonathan Hickling. He photographed these near Dunslop Bridge at the Forest of Bowland, Lancashire, and this was on 24th July 2018.
Should I be lucky enough to one day find this plant then I will photograph it and add my photos to this post.
The BSBI says that it is only found in 314 tetrads in the UK. They are mainly located in Wales so I might get lucky. I will need to look in damp, wet or boggy places on acidic soils, which occur on heaths, heathy pastures, moors, open woodland and Salix carr, and by streams and in flushes.
The flowers are light blue with a slightly darker vein down the centre of each of the five petals that fuse together to make the bell. Although in one photo it looks like four petals???They are also very small but looking like the typical bellflower. They are held singly on long delicate stalks. Also not surprisingly the leaves are ivy shaped, in fact very similar to ivy-leaved toadflax.
