Cerro Hawthorn (Erythropoda)

The Cerro Hawthorn (Erythropoda) is generally described as a perennial tree or shrub. This is native to the U.S. (United States) has its most active growth period in the spring and summer . The Cerro Hawthorn (Erythropoda) has dark green foliage and inconspicuous white flowers, with a moderate amount of conspicuous black fruits or seeds. The greatest bloom is usually observed in the late spring, with fruit and seed production starting in the summer and continuing until winter. Leaves are not retained year to year. The Cerro Hawthorn (Erythropoda) has a short life span relative to most other plant species and a slow growth rate. At maturity, the typical Cerro Hawthorn (Erythropoda) will reach up to 16 feet high, with a maximum height at 20 years of 24 feet.

The Cerro Hawthorn (Erythropoda) is not commonly available from nurseries, garden stores and other plant dealers and distributors. It can be propagated by seed. It has a moderate ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -50°F. has low tolerance to drought and restricted water conditions.

Uses of : Landscaping, Medicinal, Culinary, etc.

Erosion Control: Because cerro hawthorn tolerates a wide variety of sites, it can be planted to stabilize banks, for shelterbelts, and from wind and water erosion.

Timber: Although the wood is hard and strong, it has no commercial value except for tool handles and other small items.

Wildlife: It provides excellent cover and nesting sites for many smaller birds. Birds, rodents, and other smaller mammals eat the small fruits.

Beautification: Excellent for environmental plantings including small specimen tree and shrub border.

General Characteristics

General: Rose Family (Rosaceae). It is a native shrub or small tree that grows to sixteen feet high, with dense spreading, glabrous branchlets and sharply thorny. Leaves are broadest near the base or middle, dark green, smooth at maturity, and sometimes shallowly lobed. Flowers are white and produced in clusters of five to ten flowers. Fruits are elongated, red to blackish in color.

Required Growing Conditions

Cerro hawthorn grows from Washington to Wyoming, and south to Arizona and New Mexico.

Adaptation Although it will succeed in partial shade and different soil types, it grows best in full sunlight and well-drained loamy soils. Cerro hawthorn will tolerate wet soils before becoming drought tolerant once established. It is wind tolerant, making it a good tree species in shelterbelt planting. It is also tolerant of atmospheric pollution and performs well in urban settings.

Cultivation and Care

Propagation from Seed or Grafting: Cerro hawthorn can be propagated by either seeds or grafting. Successful propagation using seeds requires acid scarification followed by warm stratification and prechilling. Seeds, whose numbers per lb. varies with species, are planted early in the fall, in drill rows eight to twelve inches apart and covered with 1/4 inch of soil. Seedlings must not be kept in the nursery longer than a year.

Containerized trees should be planted when they are no more than eight feet tall, in the fall or spring. Balled and burlapped trees should be planted in early spring.

Grafting on seedling stock of Crataegus oxyacantha or Crataegus monogyna is best carried out in the winter to early spring.

General Upkeep and Control

Pruning should be done in the winter or early spring in order to maintain a clear shoot leader on young trees and/or remove the weakest branches to allow more light to pass through. Suckers or stems arising from the roots should be removed when they become noticeable.

Pest and Potential Problems Although insects and diseases seldom affect cerro hawthorn it is susceptible to fireblight, cedar-hawthorn rust, cedar-quince rust, leaf blight, fruit rot, and leaf spot.
