Hawthorns comprise the single largest group of trees and large
shrubs that inhabit the woods and fields of Ohio, based upon the
number of native and naturalized species (more than 60), even
outnumbering the Oaks (over 20). They are known primarily for
their white spring flowers, late summer and autumn fruits
(yellow, orange, or red in color), and their twiggy, thorny
canopies. Growth is usually slow, and their preference is for
sunny sites under a variety of soil conditions, tolerating
summer drought very well. In general, they have an upright to
rounded growth habit in youth, becoming spreading as they
mature. Hawthorns tend to colonize pastures, where their thorns
prevent cattle and other domestic animals from grazing on them
while they are young or mature. Heights range from 10 to 25
feet, and widths about 15 to 30 feet. As members of the Rose
Family, they are related to the Serviceberries, Chokeberries,
Crabapples, Plums, Cherries, Pears, and Roses, as well as many
other genera of ornamental and economic
