I have 2 grafted acers that I'd like to know the mature h x w of.

1. Acer palmatum 'Sango-kaku'

- the rootstock is 4" tall

- the scion is 4.5' tall

2. Acer palmatum 'Butterfly'

- the rootstock is 4" tall

- the scion 3' and weeping in habit

* I know so little about grafting, and it's effect on growth
