Hairy St Johns-wort: the hairy hypericum | Nature Notes from Dorset

I have included hairy St John's wort (Hypericum hirsutum) in my series on woodland flowers but, in truth, it could have been included elsewhere as in addition to open woodland rides and woodland edges it occurs on river banks, in ditches and along hedgerows.
