I'm looking to get a nice present for a very keen gardener - they have a big garden and an allotment. Budget about £40 or £50 max. I was wondering whether a nice plant or bush for the garden would be a good idea - I assume there are websites where you can have them delivered? But as its winter is it not an ideal time to have something new to plant? Is there something tool-wise that is really useful? I don't really garden myself so am a bit clueless, any ideas welcome from those with green fingers!
