Dear Bob, thank you very much for your comments and the information about the Achillea. Walther Funcke sounds like a German gun to me.
You cannot write things down at these shows with over 60 pounds of camera equipment whilst holding a camera, and getting jostled by the crowds.
At Chelsea I took over 1200 pictures and did it all by knowing plants and memory!
I am glad you enjoyed it though. Not so much as I did when I got home as my wife would not let me in the house till she washed me down with the garden hose, as I was covered in mud!
Oh what fun that was, not!
Regards.
Neil.
