Sargent crabapple is an attractive compact landscape tree with abundant clusters of fragrant white flowers in the spring. The pink buds open into pure white blossoms followed by 1/3"-1/2 " berry-like fruits that turn bright red in early fall and persist on the tree into winter. Low zigzag, horizontal branching forms a dense spreading crown that exceeds the height with maturity. Routinely grown as a shrub or multi-stemmed tree, it can be pruned to a single trunk. The dark green summer leaves are smooth, and vary in shape without or with three lobes. Sargent crab prefers a sunny location with moist, well drained soil but will grow on sites with heavier and drier soils. The pea-sized fruit is a favorite of birds, and the dense foliage provides protective shelter.
The Sargent crab is an attractive, compact tree or shrub, easy to transplant and grow. The small size and dense, wide spreading crown makes it useful under utility lines if there is room for a spreading crown, confined yards or gardens, privacy screens and hedges, and on sloping ground. Its attributes for wildlife and dependable spring beauty add to its appeal for home landscaping. Fragrant, pure white flowers are borne in great profusion in the spring. The red berry-like fruit is a favorite of birds, so much so, they may strip the tree prematurely before winter. Sargent crabs are often used in bonsai.
The Sargent crab is the smallest and most shrublike of all the crabapples. It forms a rounded, dense crown with zigzag branches that become gnarled and sometimes thorny with age, spreading up to twice as wide as the tree is tall. Its bark is dark gray-brown. Routinely grown with multiple trunks, it can be trained to grow with a single trunk. The new leaves are light green with fine hairs, later turning darker green and becoming smooth. The sweetly fragrant white flowers are abundant and produced in attractive clusters in May. The bright red, pea-sized pomes hang on the tree in clusters. This tree prefers moist, acidic loam, but will grow on sites with heavier and drier soils. It can be propagated by grafting or budding, softwood cuttings taken in early summer, or by seed. Seed propagation can result in size variations. Reported to be slightly susceptible to fireblight, it is also said to be resistant to scab, leaf spot, and the attacks of Japanese beetles.
The wildlife value is very high. The pea-sized fruits make is easy for birds of many species to pluck and swallow. They are especially favored by cedar waxwings, robins, grosbeaks, and mockingbirds.
