Phonetic Spelling:krah-TEE-gus KOL-in-uh

Genus:Crataegus

Species:collina

Family:Rosaceae

The Hawthorn genus encompasses a variety of species and forms that are indigenous to North Carolina, thriving in diverse environments ranging from the low-lying swamps and riverbanks in the east to the mountainous ridges in the west. One notable species is Crataegus collina, commonly known as Hillside Hawthorn. This deciduous shrub or small tree, characterized by its flat-topped, horizontally spreading branches, is part of the rose family and can be found in the open hardwood and coniferous forests of the North Carolina mountains at lower elevations. Hillside Hawthorn is occasionally cultivated for ornamental purposes and offers numerous advantages for wildlife, including food, nesting habitats, and shelter for birds, bees, and small mammals.

This tree thrives in full sun to partial shade and favors moist, well-drained soils. In spring, it produces flowers that give way to edible yellow to orange pomes, which are particularly attractive to bees, wasps, birds, and small mammals. However, it is sensitive to drought conditions and may lose its leaves by mid-August during particularly hot summers. The branches are equipped with 2-inch thorns, though not as densely as some other hawthorn species.

In terms of vulnerabilities, the Hillside Hawthorn is quite prone to rust and has numerous thorns, which can make fruit drop a messy affair.

Important nectar flower for insects; food plant of many moths including the eggar moth; haws provide winter fruit for songbirds. This plant also provides nectar for pollinators. It is a larval host plant for Gray Hairstreak (Strymon melinus), Red-spotted Purple (Limenitis arthemis astyanax), and Viceroy (Limenitis archippus). Red-spotted Purple and Viceroy rarely use this host plant in North Carolina. Good nesting habitat with thorns providing protection from predators.
