Botanical Description
Growth Habit:
Crataegus monogyna is a deciduous shrub or small tree, reaching heights of 5-15 meters. It features a dense, thorny structure, often used in hedgerows and as a natural fence in traditional landscapes. It is long-lived, sometimes reaching over a century old.
Leaves:
The leaves are deeply lobed, dark green, and glossy on the upper surface, with a more textured, paler underside. They are arranged alternately along the thorny stems.
Flowers:
The flowers bloom in late spring, forming clusters of small, fragrant white or pale pink blossoms. The five-petaled flowers are beloved by pollinators, particularly bees, and give the tree its common name, Mayblossom.
Fruits (Haws):
Hawthorn produces small, red berries known as haws, which appear in autumn and remain on the tree well into the winter. These fruits are about the size of small cherries, containing one large seed (monogyna species) or sometimes more in other species. Haws are rich in nutrients and used both medicinally and as food.
Thorns:
Sharp thorns up to 1-2 cm long grow along the branches, giving the tree its common names like Quickthorn and Whitethorn.
Habitat:
Crataegus spp. thrive in temperate regions and are commonly found in hedgerows, woodland edges, and open fields throughout Europe, Asia, and North America. They prefer well-drained soil and can tolerate partial shade but thrive in full sun.
