Sussex Carole, I have searched through all my wild flower books and have been unable to identify that yellow flower you found, the pink ones with fern like leaves are Herb Robert, the other pink ones are Red Campion. The violet was the common Dog violet, but the smaller ones we saw earlier may have been sweet violet. The white flower is Greater Stitchwort. I think that was all the ones we were not sure about the names of!
Vaughan! You weren't supposed to tell them we didn't really make it last year! - I have photos to prove we did this year and will post them just as soon as I get time!
Cheers, Lucy
