As with most forums, have a lurk around a few and see which has the fewest cocks crowing on it (and hens bleating!!!)
As said above, there's a reasonably knowledgeable crowd on this forum so it's always worth asking here.
If possible, try to find as local a forum as possible since suitable plants can vary hugely depending on local microclimate, soil type and drainage so what might thrive down here in Devon would keel over and turn up its toes on the Yorkshire dales.
