I'd like to buy a couple of big shrubs for my garden but all of the garden centres I've been to only have small or - at best - medium size ones. I've bought a few but even two years on, everything is still teeny and underwhelming. Where should I be going? Should I go to nurseries instead of garden centres - is that where these things are actually grown? I'm based in the south east, near the Surrey/London border.
I was just watching Love Your Garden and they planted a huge (6ft) viburnum popcorn, which was gorgeous - where do I get such things?!
