Hi I'm new to gardening and have a south facing garden in the new house I've moved to. I'd love to get an acer tree that has deep red leaves for as much of the year as possible but won't grow to be a monster. I've seen a beautiful one on my drive to work that is only about 8 feet high and has grown over into a sort of umbrella shape, it's gorgeous but I'm not sure if the owner has pruned it to be like that or if it's naturally grown. Does anyone have any advice? Thanks.
