Family:Rosaceae

Crataegus, commonly known as Hawthorn, is a genus that encompasses a variety of shrubs and small trees found throughout North Carolina, thriving in diverse environments ranging from eastern swamps and low riverbanks to the elevated mountain ridges in the west. One notable species is Crataegus pruinosa, or Waxy-fruited Hawthorn, which is indigenous to much of the Eastern United States and Canada. This species exhibits considerable variation depending on its geographical location and is sometimes classified as multiple species. It typically flourishes along woodland edges, rocky slopes, stream banks, and roadsides. The term "pruinosa" in its species name refers to the waxy coating that appears on its fruits.

Like many Hawthorn species, the Waxy-fruited Hawthorn features straight thorns measuring about 2.5 inches in length, produces white flowers in the spring, and bears red fruit that develops a whitish, waxy surface as it ripens. The tree has an irregular branching pattern, can grow up to 20 feet tall, and may have a trunk diameter of up to 8 inches. This species is relatively easy to cultivate, thriving in full or partial sunlight and preferring well-drained, moist to wet soil, particularly in loam or clay-loam with some rocky elements. Planting in full sun enhances fruit production, while shaded areas may result in lower yields. When grown from seed, it typically takes 5 to 8 years for the trees to begin fruiting, whereas grafted specimens may produce abundant flowers by their third year. The Waxy-fruited Hawthorn is resilient to strong winds and drought conditions but struggles in coastal areas with salt exposure. It is often challenging to find this tree available for purchase commercially.

**Diseases, Insects, and Other Plant Issues:**

Currently, there are no significant issues reported. However, cedar-apple rust can cause discoloration and weaken the leaves.

Important nectar flower for insects and other pollinators; food plant of many moths including the eggar moth; haws provide winter fruit for songbirds and mammals. 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.
Fruit can be eaten raw or cooked. The flesh is thick, sweet and yellow. The fruit can be used for pies, preserves, and can dried for later use.
