I know Ron Kirkman and he came down and did some speaking at Rosemoor
when I organised a Clematis weekend there, he certainly knows his stuff.


But there is a very good list as well that you can download from the RHS
site with subjects and prices etc. and a bit about the speakers. There
is a also a list for gardening speakers .

Nothing beats a recommendation though.
