We want a tree for our front garden. It will be planted in a quarter circle bed (is that a quadrant?) with a low fence on one side and a low wall on the other. We want something that gives some interest for as much of the year as possible and don't want it to grow too big - say 3m or so. Perhaps a shrub would be better.
I've looked at the Crocus site but nothing fits the bill. Are there other websites I can search on?
