Additional Information

Well adapted to different light (even shade) and soil conditions, especially to dry situations. Relatively trouble-free, and one of the most fragrant of the mockoranges. None of the mockoranges have much landscape interest after the season of bloom. Becomes leggy if not pruned. Pruning should be done after flowering (flower buds form on previous years wood), and to maintain fullness of form.
