Crataegus monogyna, known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and Western Asia, but has been introduced in many other parts of the world.
This species is one of several that have been referred to as Crataegus oxyacantha , a name that has been rejected by the botanical community as too ambiguous. In 1793, Medikus published the name C. apiifolia for a European hawthorn now included in C. monogyna, but that name is illegitimate under the rules of botanical nomenclature. [4] [5]
Other common names include may, mayblossom, maythorn, (as the plant generally flowers in May) quickthorn, whitethorn, motherdie, and haw.
The common hawthorn is a shrub or small tree up to about 10 metres (33 feet) tall, [6] with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear sharp thorns, about 12.5 millimetres (1⁄2 inch) long. The leaves are 20 to 40 mm (3⁄4 to 1+1⁄2 in) long, obovate, and deeply lobed, sometimes almost to the midrib, with the lobes spreading at a wide angle. The upper surface is dark green above and paler underneath.
The hermaphrodite flowers are produced in late spring (May to early June in its native area) in corymbs of 5–25 together; numerous red stamens and a single style; they are moderately fragrant. The flowers are white, frequently pink [7] pollinated by midges, bees, and other insects, and later in the year bear numerous haws. The haw is a small, oval, dark red fruit about 10 mm long, berry-like, but structurally a pome containing a single seed. Haws are important for wildlife in winter, particularly thrushes and waxwings; these birds eat the haws and disperse the seeds in their droppings.
The common hawthorn is distinguished from the related but less widespread Midland hawthorn (C. laevigata) by its more upright growth, the leaves being deeply lobed, with spreading lobes, and the flowers having just one style, not two or three. They are interfertile, however, so hybrids occur frequently; they are only entirely distinct in their more typical forms.

Ireland and Britain [8] The mountains are very young in the Eastern Anatolian region of Turkey. Therefore, the trees in the region multiply with seeds.[ citation needed ]
Due to excessive animal grazing in the area, new shoots of vulnerable Crataegus monogyna trees in the open field are eaten by animals. This does not allow them to grow and causes them to take a horizontally irregular shape on the ground.[ citation needed ]
A study in Wales indicted that current levels of overgrazing by sheep might extirpate the species in 60-70 years. [9]
The fruit of hawthorn, called haws, are edible raw [10] but commonly made into jellies, jams, syrups, or wine, or to add flavour to brandy. Botanically, they are pomes, but they look similar to berries. A haw is small and oblong, similar in size and shape to a small olive or grape, and red when ripe. The haws develop in groups of two or three along smaller branches. They are pulpy and delicate in taste. In this species (C. monogyna), they have only one seed, but other species of hawthorn may have up to five seeds.
The petals are also edible, [11] as are the leaves, which if picked in spring when still young are tender enough to be used in salads. [12] Hawthorn petals are used in the medieval English recipe for spinee, an almond milk-based pottage [13] [14] recorded in 'The Forme of Cury' by the Chief Master-Cook of King Richard II, c. 1390.
C. monogyna is one of the most common species used as the "hawthorn" of traditional herbalism. The plant parts used are usually sprigs with both leaves and flowers, or alternatively the fruit ("berries"). [15] Hawthorn has been investigated by evidence-based medicine for treating cardiac insufficiency. [15]
C. monogyna is a source of antioxidant phytochemicals, especially extracts of hawthorn leaves with flowers. [16]

Common hawthorn is extensively planted as a hedge plant, especially for agricultural use. Its spines and close branching habit render it effectively livestock- and human-proof, with some basic maintenance. The traditional practice of hedge laying is most commonly practised with this species. It is a good fire wood, which burns with a good heat and little smoke. [17]
Numerous hybrids exist, some of which are used as garden shrubs. The most widely used hybrid is C. × media (C. monogyna × C. laevigata), of which several cultivars are known, including the very popular 'Paul's Scarlet' with dark pink double flowers. Other garden shrubs that have sometimes been suggested as possible hybrids involving the common hawthorn,[ citation needed ] include the various-leaved hawthorn of the Caucasus, which is only very occasionally found in parks and gardens.
In pre-modern Europe, hawthorn was used as a symbol of hope, and also as a charm against witchcraft and vampires. [18] Hawthorn was believed by some to have the ability to inhibit intruding supernatural forces, and was also thought to be sacred in nature due to an association between the hawthorn bush and the crown of thorns that, according to the New Testament, was placed on Jesus. [19]
As protection against witchcraft, hawthorn was sometimes placed in the cradles of infants, or around houses and doorways. [18] The Greeks reportedly placed pieces of hawthorn in casement windows to prevent witches from entering houses, [20] while Bohemians placed hawthorn on the thresholds of cow houses for the same purpose. [19] Hawthorn was sometimes placed on the coffin of a deceased person, on top of the person's corpse, or in the corpse's sock. [19] In Bosnia, women would sometimes place a piece of hawthorn behind the headcloth of a recently deceased person, and then throw away the remaining twig on their way home. [19] If the deceased person was a vampire, it would focus its attention on the hawthorn instead of following the woman home. [19] Among the South Slavs, stakes made of hawthorn or blackthorn wood were considered effective in impaling vampires. [21]
An ancient specimen, and reputedly the oldest tree of any species in France, is to be found alongside the church at Saint Mars sur la Futaie, Mayenne. [22] As of 2009, the tree had a height of 9 m (30 ft) and a girth of 2.65 m (8+1⁄2 ft). The inscription on the plaque beneath reads: "This hawthorn is probably the oldest tree in France. Its origin goes back to St Julien (third century)"; this has not yet been verified. A famous specimen in England was the Glastonbury or Holy Thorn which, according to legend, sprouted from the staff of Joseph of Arimathea after he thrust it into the ground while visiting Glastonbury in the first century AD. The tree was noteworthy because it flowered twice in a year, once in the late spring which is normal, but also once after the harshness of midwinter had passed. The original tree at Glastonbury Abbey, felled in the 1640s during the English Civil War, [23] has been propagated as the cultivar 'Biflora'. [24] A replacement was planted by the local council in 1951, but was cut down by vandals in 2010. [23]
The oldest known living specimen in East Anglia, and possibly in the United Kingdom, is known as the Hethel Old Thorn, [25] and is located in the churchyard in the small village of Hethel, south of Norwich, in Norfolk. It is reputed to be more than 700 years old, having been planted in the thirteenth century. [25]
Crataegus, commonly called hawthorn, quickthorn, thornapple, May-tree, whitethorn, Mayflower or hawberry, is a genus of several hundred species of shrubs and trees in the family Rosaceae, native to temperate regions of the Northern Hemisphere in Europe, Asia, North Africa and North America. The name "hawthorn" was originally applied to the species native to northern Europe, especially the common hawthorn C. monogyna, and the unmodified name is often so used in Britain and Ireland. The name is now also applied to the entire genus and to the related Asian genus Rhaphiolepis.
Crataegus mollis, known as downy hawthorn or red hawthorn, is a species of plant that occurs in eastern North America from southeastern North Dakota east to Nova Scotia and southwest to eastern Texas. The range of this species is from southern Ontario and Michigan to eastern North Dakota and southward to Denison, Texas, and Arizona. This tree inhabits wooded bottomlands, the prairie border, and the midwest savanna understorey.
The Glastonbury thorn is a form of common hawthorn, Crataegus monogyna 'Biflora', found in and around Glastonbury, Somerset, England. Unlike ordinary hawthorn trees, it flowers twice a year, the first time in winter and the second time in spring. The trees in the Glastonbury area have been propagated by grafting since ancient times. The tree is also widely called the holy thorn, though this term strictly speaking refers to the original (legendary) tree.
Crataegus heterophylla, known as the various-leaved hawthorn, is of uncertain origin. Its original native range is not known, possibly it was the Caucasus of Western Asia. Suggestions that it originated in Southeast Europe may be based on misidentification.
Crataegus laevigata, known as the Midland hawthorn, English hawthorn, woodland hawthorn, or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain and Spain east to the Czech Republic and Hungary. It is also present in North Africa. The species name is sometimes spelt C. levigata, but the original orthography is C. lævigata.
Crataegus douglasii is a North American species of hawthorn known by the common names black hawthorn and Douglas' thornapple. It is most abundant in the Pacific Northwest.
Crataegus flava, common names summer haw and yellow-fruited thorn, is a species of hawthorn native to the southeastern United States from Virginia to Florida, west to Mississippi. Due to an error by Sargent the name C. flava was, and often still is, used for a different species C. lacrimata, which belongs to a different series, the Lacrimatae series. Flavae is another group of species that were thought to be related to the misidentified C. flava, and although it is now apparent that they are not related, the name of the group remains. Because the true identity of this species has only recently been discovered, the name is rarely used correctly. Individuals with red fruit occur; these have sometimes been assigned to a separate species, Crataegus senta.
Crataegus crus-galli is a species of hawthorn known by the common names cockspur hawthorn and cockspur thorn. It is native to eastern North America from Ontario to Texas to Florida, and it is widely used in horticulture. It is thought to be the parent, along with Crataegus succulenta, of the tetraploid species Crataegus persimilis.
Crataegus erythropoda is a hawthorn native to the southern Rocky Mountains in the United States. The leaves are conspicuously shiny above and fruit ("haws") are dark purplish red. It is seldom cultivated, but at one time was listed in the nursery trade under the common name "Chocolate Haw". It is closely related to C. rivularis which has fruit that are fully black when ripe.
Crataegus punctata is a species of hawthorn known by the common names dotted hawthorn or white haw that is native to most of the eastern United States and eastern Canada. While some sources claim it is the state flower of Missouri, the actual legislation does not identify an exact species. Furthermore, the Missouri Department of Conservation asserts the Crataegus mollis was specifically designated as the state flower.
Crataegus rhipidophylla is a species of hawthorn which occurs naturally from southern Scandinavia and the Baltic region to France, the Balkan Peninsula, Turkey, Caucasia, and Ukraine. It is poorly known as a landscape and garden plant, but seems to have potential for those uses.
Crataegus × media, is a hybrid between two species in the genus Crataegus (Hawthorn), C. monogyna and C. laevigata, both in series Crataegus. Under the rules of botanical nomenclature the name C. × media covers all intermediate forms between the two parent species, including backcrosses.
Crataegus mexicana is a species of hawthorn known by the common names tejocote, manzanita, tejocotera and Mexican hawthorn. It is native to the mountains of Mexico and parts of Guatemala, and has been introduced in the Andes. The fruit of this species is one of the most useful among hawthorns.
Crataegus × macrocarpa, is a hybrid between two species of Crataegus (hawthorn), C. laevigata and C. rhipidophylla, both in series Crataegus. A chemotaxonomic investigation comparing flavonoid patterns in C. × macrocarpa and its putative parent species corroborated their supposed relationship. It is sometimes confused with C. × media, the hybrid between C. monogyna and C. laevigata.
Phyllonorycter oxyacanthae is a moth of the family Gracillariidae found in all of Europe except the Balkan Peninsula. It was described by the German-born Swiss entomologist, Heinrich Frey in 1856. The larvae are known as leaf miners, living inside the leaves of their food plants.
Stigmella oxyacanthella is a moth of the family Nepticulidae, found in Europe and North America. The larvae are leaf miners feeding inside the leaves of trees and shrubs, such as hawthorn, apple and pear.
Stigmella hybnerella also known as the greenish thorn pigmy is a moth of the family Nepticulidae. It is found in all of Europe, in North Africa, the Near East, and the eastern part of the Palearctic realm. The larvae mine the leaves of trees and shrubs such as hawthorns and rowans.
Stigmella crataegella is a moth of the family Nepticulidae found in Europe. It was described by the Austrian entomologist Josef Wilhelm Klimesch in 1936. The larvae mine the leaves of hawthorns.
Crataegus brainerdii is a species of flowering plant in the rose family known by the common name Brainerd's hawthorn. It is named for Ezra Brainerd (1844–1924), a renowned botanist and former president of Middlebury College, in Vermont.
Crataegus persimilis is a species of hawthorn, known by the common names plumleaf hawthorn and broad-leaved cockspur thorn, native to southern Ontario, Canada, and the US states of New York, Pennsylvania, Ohio, Kentucky, West Virginia, and Virginia. It is widely cultivated, particularly in Europe, as an ornamental. Its sporadic distribution in its natural range and certain of its morphological characters leads authorities to consider it a probable naturally occurring hybrid, with its most likely parents being Crataegus succulenta and Crataegus crus-galli. It is a tetraploid. Some populations may be self-perpetuating. Its 'Prunifolia' cultivar has gained the Royal Horticultural Society's Award of Garden Merit, and is considered one of its top 5 trees for smaller gardens.
