Unfortunately there are practically none around here in Cov. In fact I only
know one decent commercial grower, and he only sells about 8 different
plants! ... Just as well I like growing seedlings, all things considered!

Have you not tried Smiths up past Baginton airport (just outside
Coventry) - it is an excellent plant nursery, run and owned by the same
family for years - it is not a garden centre but has an excellent range
in plants.
