Hi Sam
Hope your feeling better, sorry we started without you but great idea.
I lots of seeds from a wildflower garden I sowed last year, I originally bought the seeds for bees and butterflies and for birds and insects. I have some research to do to see exactly what the flowers are but happy to send some.
It was an easy job and a beautiful result with very little effort and I now have a bee's nest (not sure what type of bees but they go into a small holes at the side of the greenhouse).
I am just trying to get hold of a book recommended by Nutcutlet to identify the flowers but I took lots of photo's so I will see if I can post some later 
And thanks Gardengirl thats great .
