Franz,

The RHS plantfinder is on the net. I use it quite regularly. The URL
is

http://www.rhs.org.uk/rhsplantfinder/plantfinder.asp

That's exactly where I have been and where I got the bad results....

It is possible that you might have to be a member of the RHS to have
access to it, but give it a try.

This can't be - otherwise I would have got no result with *any* search.

Bye, Gaby
