Nobody needs to plant a birch, poxy fally overy, shallow rooted, crap timber weeds. I don't care that they're pretty, the pollen gives me another excuse to despise them.
What size? - if its small/mid-size after much research, I went for a Mount Fuji Cherry tree (Prunus Shirotae) which like Colins suggestion creates a nice create almost flat-topped canopy.
