Maackia is useful where space would restrict a large growing shade tree. This Asian species of Yellowood produces creamy white flowers in early summer but is better known for its handsome blue green foliage and golden bark which resembles somewhat the bark of a cherry or yellow birch. The tree matures gracefully into a gently arching rounded vase. Maackia has received high marks for adapting to conditions in the Midwest including restricted root zones and high pH. Thus far, it appears to be quite happy in our Zone 8 nursery.
