Additional Information

The Flowering Crabapple is a popular small ornamental tree with an extremely showy flower display in the spring. Malus x zumi 'Calocarpa' is an annual (sometimes alternate) bloomer that has red buds opening to fragrant pale pink or white. Flowers are followed by numerous, persistent, bright red fruits. This plant has slight susceptibility to apple scab, powdery mildew, and cedar-apple rust, and is highly susceptible to fireblight. Well-drained heavy loam soils and full sun promote best growth. May look ragged at the end of the summer.
