What is Sargent Crabapple?
Sargent crabapple, scientifically known as Malus Sargentii, is a deciduous tree belonging to the Rosaceae family. It is native to East Asia, particularly Japan, Korea, and parts of China. This species was named after Charles Sprague Sargent, an American botanist, and the director of the Arnold Arboretum. Sargent crabapple is valued for its ornamental features, including its profuse spring blossoms, small crabapples, and vibrant autumn foliage.
Characteristics of Malus Sargentii
Sargent crabapple is characterized by its compact, spreading growth habit and a rounded crown. The tree typically reaches a height of 8 to 15 feet, with a slightly greater spread. Its dark green, serrated leaves turn shades of orange, red, and yellow in the fall, creating a stunning display of autumn colors. During spring, the tree produces delicate, fragrant white or pink blossoms, which give way to small, berry-like fruits in late summer. The fruits, which are typically red or yellow, persist throughout the fall and often attract wildlife such as birds.
