Cockspur Hawthorn (Crus-galli) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by
bare root, container, seed.
It has a
moderate ability to spread through seed production and the seedlings have
Note that cold stratification is
not required for seed germination and the plant cannot survive exposure to temperatures below
high tolerance to drought and restricted water conditions.
Uses of : Landscaping, Medicinal, Culinary, etc.
Erosion Control: Because it tolerates a wide variety of sites, it can be planted to stabilize banks, for shelterbelts, and for erosion control.
Wildlife: It provides excellent cover and nesting sites for many smaller birds. The small fruits are eaten by many birds especially cedar waxwings, fox sparrows, and ruffed grouse; rodents and other smaller birds. White tailed deer and mule deer browse the young twigs and leaves.
Beautification: Excellent in group plantings, deciduous screens, groupings, tall barrier hedge, and seasonal accent tree.
General: It is a small tree that grows twenty to thirty feet high, twenty to thirty-five feet wide; with wide-spreading, horizontal, thorny branches. Leaves are broadest above or near the middle, thick, leathery, shiny dark green above, usually not lobed, and smooth. Flowers ranging from white to red are produced in clusters.

Required Growing Conditions
Cockspur hawthorn grows from southern Quebec, and Ontario to northern Louisiana, Alabama and northwestern Georgia, and west to Kansas.
Adaptation Although Cockspur hawthorn generally requires no special soil requirements, it prefers a moist, well-drained, slightly acid soils, and full sunlight. It is adaptable to poor soils; various soil pHs, compacted soils, drought, heat and winter salt spray. Adapted to USDA Hardiness Zone 4.
Cultivation and Care
Propagation from Seed or Grafting: Cockspur hawthorn can be propagated by seeds or by stem cuttings grafted onto seedling rootstock. Propagation using seeds requires acid scarification for two to three hours followed by three months warm stratification and another three months prechilling. Seeds are planted in drill rows eight to twelve inches apart and covered with 1/4 inch of soil.
Containerized trees should be planted when they are no more than eight feet tall, in the fall or spring.
Grafts are budded on seedling understock in August and September.
General Upkeep and Control
Seedlings develop taproot thus should not be kept in seedbeds longer than one year. Balled and burlapped trees should be planted in early spring. If transplanted in autumn, amend soil, fertilize, water thoroughly, mulch adequately and avoid winter salt spray. 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 Cedar hawthorn rust affects the fruit, foliage and stems. Potential pests include leaf blotch minor.
