Princess Diana Serviceberry Tree

‘Princess Diana’ is an apple serviceberry with abundant white spring flowers, dark edible berries and bright red autumn foliage. It develops a rounded, spreading crown and can be used as a specimen or in a larger mixed border where its mature width will not crowd nearby plants. ## Landscape use and seasonal interest The University of Illinois identifies the cultivar by name, describing an oval-rounded, multi-stemmed plant with heavy white flowering and brilliant red fall color. Its [cultivar record](https://woodyplants.nres.uiuc.edu/plant/amegrpd) gives a mature height of 20–25 feet. Iowa State notes the cultivar’s spreading habit, abundant fruit and red fall color. Serviceberry flowers are short-lived but valuable early-season forage; berries may feed birds and can be used as food when correctly identified and sound. ## Size and siting Allow roughly 20–30 feet of height and a broad, spreading crown; Minnesota Extension lists 30 feet tall by 20 feet wide, while Illinois gives 20–25 feet tall. These are source ranges, not a precise single size. Plant in full sun to part shade in moist, well-drained soil. More sun generally favors flowering and fruiting. The hybrid is commonly grown as a small, multi-trunked tree or large shrub. See [Iowa State Extension](https://yardandgarden.extension.iastate.edu/how-to/serviceberries) and the [University of Minnesota guide](https://extension.umn.edu/garden-and-home/yard-and-garden/lawns-and-landscapes-in-minnesota/trees-and-shrubs/serviceberry) for landscape context. ## Maintenance Water during establishment and extended dry periods. Remove dead or crossing branches after flowering; retain the natural spreading framework unless clearance requires selective pruning. Watch for leaf spot or rust in humid conditions and remove diseased litter where practical.
