So I have decided (after quite a bit of research) to replace two Japanese maples that don't look like they'll survive the winter with two smoke bushs or smoketrees. I am looking for the following (in order of importance):
1. One red and one yellow. They must be these colors in spring and summer.
2. Winter resistant (live in zone 5b).
3. The larger, the better.
4. Great fall color.
Can anyone make recommendations on specific named cultivars? Thanks!
