Description

Crataegus, or Hawthorn, is a genus of shrub or small tree containing many species and varieties distributed across North Carolina from swamps and low river bottoms in the east to higher mountain ridges in the west. Crataegus pruinosa, or Waxy-fruited Hawthorn, is a native shrubby tree in the rose family found over much of the Eastern United States and Canada. It can be variable depending on the part of the country it is found and is sometime considered more than one species. It tends to grow in woodland margins, rocky hillsides, stream banks and roadsides. The species name pruinosa refers to the waxy bloom or frosting on the fruits.

Like most Hawthorns, Waxy-fruited Hawthorn, has 2.5 inch long, straight thorns, white flowers that occur in Spring, and fruit that matures to red and has a whitish waxy coating. The tree branches irregularly and widely and reaches a height of 20 feet with a trunk up to 8 inches across. Waxy-fruited Hawthorn is easy to grow and prefers full or partial sun in well-drained but moist or wet soil conditions in loam or clay-loam soil with some rocky materials. Siting the plant in full sun will encourage fruit quantity, with lower yields in shaded conditions. When grown from seed, trees take from 5 to 8 years before they start bearing fruit; grafted trees will often flower heavily in their third year. It tolerates strong winds and drought, but does not do well in maritime conditions with exposure to salt air. This tree is difficult to find sold commercially.

Diseases, Insects, and Other Plant Problems:

No known problems. Cedar-apple rust can discolor and weaken the foliage.
