Cumulus Serviceberry is a small multi-stem tree with an upright to rounded, open form and low canopy. Clusters of showy white flowers blossom in the spring prior to the leaves emerging, and produce blue fruits. The dark green foliage turns bright orange to tomato red in the fall. Minimal suckering, a medium growth rate, and tolerance to some urban pollution make this a good choice for use in smaller landscapes and under power lines. A Treesearch introduction.
