I've been asked to find a suitable tree for a restricted space and I'm not convinced it's possible.
It couldn't be any taller or have an overall spread bigger than roughly 2 metres. Pretty much everything I've found (and I've researched quite thoroughly) will grow much bigger than that. It also really needs to have a nice, rounded shape. Ideally I'd like some nice autumn interest so colourful foliage would be good, but I'm drawing a blank so far (love the idea of a forest pansy but again, too big).
I'd go for an acer but it's a windy/cold site so that's no good. Now thinking of a large shrub but thought I'd ask here for any ideas I've missed. Help me, MN gardening experts!
I'm wondering whether I could make a multi-stemmed amelanchier lamarckii work - it would have to be kept in check as it's a bit too big really, but would otherwise be a good candidate (thanks awkwardturtle for suggesting an amelanchier).
