American mountain-ash is a striking native small tree or large shrub best suited to cool northern climates, where it thrives in moist, well-drained acidic soils in full sun to part shade. Its flat-topped white flower clusters in late spring give way to vivid orange-red berry clusters that persist into winter and are a magnet for birds. Provide consistent moisture, especially in warmer regions, and avoid hot, dry or polluted urban sites.
