Description

Hillside Hawthorn is a deciduous native shrub or small tree in the rose family.  It does not tolerate drought well and is often leafless by mid-August during hot summers. It can be found in the NC mountain area in open, hardwood & conifer-hardwood forests at lower elevations. The branches are armed with 2-inch thorns although not as many as some hawthorns. Hillside Hawthorn provides many benefits for birds, bees and mammals including food, nesting sites and cover.

This tree will grow in sun to partial shade and prefers moist well-drained soils. The flowers appear in spring and are followed by a yellow to orange pome that is edible and a favorite of bees, wasps, birds and small mammals.

Insects, disease and other problems: Quite susceptible to rust. Numerous thorns. Fruit drop could be messy.
