The genus crataegus includes about two hundred species of deciduous trees and shrubs, originating in Europe, Asia and North America; they have erect habit and produce a disordered crown, the shrubs reach 3-4 meters in height, the trees reach a maximum height of 6-8 meters. The leaves are dark green, deciduous. In spring the Hawthorn, Crataegus Laevigata produces small flowers with five petals, white or pink, simple; there are numerous hybrids with flowers with showy colors, often double or stradoppi. In summer, the flowers are followed by oval red berries, which generally remain on the plant throughout the winter. The fruits are edible, and can be used to prepare tasty jams.

These plants prefer sunny or partially shady locations; most species do not fear the cold. They are very vigorous and robust trees and shrubs, resistant to bad weather and pollution, they are often used in street trees.

With a sunny exposure the hawthorn will have greater strength and produce a more luxuriant flowering.
The hawthorn, Crataegus Laevigata, is a rather resistant plant and, in general, the different varieties are satisfied with the rains, but it is advisable to water the specimens recently planted in the summer, waiting for the soil to dry perfectly between one watering and the other. 'else. Obviously it is useful to make a distinction between plants placed in the open ground, and specimens cultivated instead in pots. For the latter the needs are different, as the land at their disposal is smaller and undergoes the drying process more quickly. When, on the other hand, the hawthorn is planted in the ground, it will be able to better exploit the humidity of the soil and its needs will be less. Obviously, in periods of greater drought there will be need for more frequent watering to counteract the effects of the hot climate.
The Hawthorn, Crataegus Laevigata grow without problems in any terrain, preferring a calcareous soil, not particularly rich in organic material, but soft and deep. The ideal soil for this plant should be well drained, to avoid possible dangerous stagnation of water that could damage it and should allow the free development of the roots, so as to have a greater growth.
