We we recommended the liquidamber by the council who have some oversight over any tree replacement here (Bracknell). And good advice it was, too. Everyone comments upon it - vistors and neighbours alike - in the autumn when it puts on its finery!
We prune it agressively every 3 years and it never fails to return with more foliage than before.
We had fruits for two years but - silly me - I mistook them for an infestation, like those affecting some oaks. The fruits rarely dropped and were on the tree next year, dark brown, hard, and not particularly attractive.
A few roots are breaking the surface which we will have to watch - unchecked, they will damage the lawnmower before too long.
Still, for the only tree we've ever purchased, this is a cracker!
