Part of the apple family, deciduous hawthorn trees (Crataegus spp.) have white spring flowers and attractive, round, edible fall fruits. Of the approximately 280 different kinds of hawthorn, most are shrubs. Tree-sized hawthorns generally grow to 25 feet tall. Native to the temperate areas of North America, Europe, and Asia, most hawthorn trees are well-armed with spines, but some thornless cultivars are available. Hawthorns are best used as accents, screens, barriers or hedges.

Thornless Trees

One of the drawbacks to using hawthorns are their spines, which make pruning and maintenance difficult. Cockspur hawthorn (Crataegus crus-Galli) has abundant thorns as long as 3 inches that can inflict serious injury. Crusader is a thornless form (Crataegus crus-Galli "Cruzam") that grows into a tree 25 to 35 feet tall and as wide. It grows in U.S. Department of Agriculture plant hardiness zones 3 through 7. The relatively thornless hybrid Lavalle hawthorn (Crataegus x lavallei) has lustrous green leaves, large orange-red fruits, and bronze-red fall foliage. It's a medium-sized tree, 20 to 30 feet tall and 15 to 20 feet wide, suitable as a street or specimen tree. Lavalle hawthorn grows in USDA zones 5 through 7a.


Colorful Fruits

Most hawthorn trees have red fruits, but some species have black or spotted fruits. Give variety to fall color by choosing a tree with a different color fruit. Black hawthorn (Crataegus douglassii) grows in western North America in USDA hardiness zones 4 through 8. The 30-foot-tall tree bears black fruits that are sweet and juicy, suitable for eating fresh or for pies and preserves. A mostly thornless variety of an eastern North American hawthorn, "Ohio Pioneer" (Crataegus punctate "Ohio Pioneer") has red berries prominently speckled with white dots. "Ohio Pioneer" grows in USDA zones 4 through 7 and can grow to 30 feet tall.


Interesting Leaves and Bark

Most hawthorns look similar. Consider varieties that have distinguishing features such as colorful bark or leaves. Washington hawthorn (Crataegus phaenopyrum), although it has green summer leaves, starts out with reddish-purple new leaves in spring and has purple, red and orange fall leaves. The white-flowered tree grows to 25 to 35 feet tall in USDA zones 4 through 8a. The silvery bark of "Winter King" Southern hawthorn (Crataegus viridis "Winter King") peels to reveal orange under-layers, making it a handsome tree even in winter when it is bare of leaves. The large, bright orange fruits and small thorns add to the tree's value. "Winter King" grows in USDA zones 4 through 7.


Exotic Species

Nonnative hawthorns from Europe or Asia make useful landscaping subjects. Chinese hawthorn (Crataegus pinnatifida) has long been grown for its berries. The thorns are short and not plentiful, and the plant grows 15 to 20 feet tall and 10 to 12 feet wide in USDA zones 6 through 8. English hawthorn (Crataegus laevigatus) is suited for urban use, withstanding conditions such as drought, air pollution, and poor soil and drainage. The species is usually white-flowered, but colorfully flowered varieties include the red-flowered "Crimson Cloud," double-flowered pale rose "Masekii" and pink-flowered "Rosea." English hawthorn and its varieties grow in USDA zones 4b through 8.
