Wildflower book?

Can anyone recommend a decent wildflower field guide for more advanced plant people:D which goes maybe into more detail and is a much more concise list of British wild flora thats not going to break the bank:rolleyes:

 

Hi Kalmia I use the Reader's Digest Field Guide to Wild Flowers it cost me 11.99 a few years ago, it's now 8.99 on play.com including delivery. The only drawback is that it can be confusing because it is set out in plant families and I prefer to look up the flower colour and work from there, but that's just my way. Hope this helps.
