The leaves are alternate and conspicuously toothed. But they vary in overall shape and are difficult to categorize. Some are slightly or deeply lobed, while others are without any sign of lobes. The small, apple-like fruit usually are red or orange in color. In some species, however, the fruit are black, dark blue, or yellow.
Hawthorns seem to prefer alkaline soils, and are most abundant in limestone areas.
They often grow on sunny abandoned fields and pasture. Taller, slower growing trees, however, shade them, suppressing their growth. The wood is without commercial value. For some people they are a desirable ornamental tree, while for others they are a weed of pasture land. A few large mammals, including cattle, sometimes browse on young growth.
