Mallow ninebark is a hardy, fast-growing native shrub that thrives in part shade with average moisture. Water regularly during the first season to establish roots, then reduce frequency as the plant becomes more self-sufficient. It requires minimal pruning — simply remove dead wood in late winter to keep it tidy.
