[3][12] The wood was formerly used for shoe lasts, nails, and veneer. Since then it has spread aggressively throughout southern Ontario and in other provinces. Glossy buckthorn, native to Europe and Asia, is a highly invasive perennial understory shrub or a small tree that can reach heights of 15 - 20 feet and 10 inches in diameter. [citation needed], The bark (and to a lesser extent the fruit) has been used as a laxative, due to its 3–7% anthraquinone content. 1994. Despite the name, glossy buckthorn has no thorns. This plant and synonyms italicized and indented above can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in different places, and some are listed above. Glossy buckthorn is native to Eurasia but has been com- monly planted in this country as a hedge and for wildlife food and cover. Alder buckthorn was first formally described by Carl Linnaeus in 1753 as Rhamnus frangula. Ready to use - do not dilute: Cut stump or basal bark: Roundup, Rodeo, Accord, Etc. Unlike other "buckthorns", alder buckthorn does not have thorns. Buckthorn may refer to one of two different species found in Minnesota: Common (or European) buckthorn ( Rhamnus cathartica) or glossy buckthorn ( Frangula alnus ). The cultivar 'Tallhedge' has been selected for hedging. Eastern white pine stands are easily invaded because they allow more light to reach the forest floor, and tree stands that are cut are very quickly invaded while undisturbed stands are rarely invaded. It is native to Europe, northernmost Africa, and western Asia, from Ireland and Great Britain north to the 68th parallel in Scandinavia, east to central Siberia and Xinjiang in western China, and south to northern Morocco, Turkey, and the Alborz in Iran and Caucasus Mountains; in the northwest of its range (Ireland, Scotland), it is rare and scattered. It is usually multistemmed, but rarely forms a small tree with a trunk diameter of up to 20 cm (8 in). Alder buckthorn is mainly used for constipation. Native to Europe, Central Asia, and North Africa, it may have been introduced for landscaping. It is also introduced and naturalised in eastern North America.[3][4][5][6][7]. ---Part Used---Bark. Do NOT bring orphaned or injured wildlife to Mass Audubon wildlife sanctuaries. For constipation: the typical dose of alder buckthorn is 0.5-2.5 grams of the dried bark. The seeds are primarily dispersed by frugivorous birds, which readily eat the fruit.[3][5][6][7][8][9]. These buckthorn species were first brought here from Europe as a popular hedging material. In fields, try frequent mowing. Common buckthorn (also known as European buckthorn) is a small shrub or tree native to Eurasia. A variegated cultivar Frangula alnus 'Variegata' and a cultivar with very slender leaves 'Asplenifolia' are sometimes grown in gardens as ornamental shrubs. Common Uses: Posts, turned objects, carvings, and other small wooden specialty items. Chokeberry leaves come to a point with a serrated edge, and theyâll often be turning a rich red color as the berries ripen. [12], Alder buckthorn grows in wet soils in open woods, scrub, hedgerows and bogs, thriving well in sunlight and moderate shade, but less vigorously in dense shade; it prefers acidic soils though will also grow on neutral soils. Since its introduction, it has spread aggressively across most of the northeast and upper Midwest and has become a serious threat to the degra⦠Uplands forests are not invaded as easily as lower lying ones. Alias names for Buckthorn: Family Rhamnaceae, Common Buckthorn, Alder Buckthorn, Glossy Buckthorn, Frangula alnus, Chinese name: Rhamnus utilis Decne About Buckthorn: Buckthorn, also called Alder Buckthorn is a deciduous shrub or small tree growing to 15 ft (5 m). [19] Frangula alnus and the related species Rhamnus cathartica have been banned from sale, transport, or import to Minnesota[20] and Illinois. It is particularly highly valued for time fuses because of its very even burn rate. Read More. Common (Rhamnus cathartica) and glossy buckthorn (Frangula alnus syn. The bark is dark blackish-brown, with bright lemon-yellow inner bark exposed if cut. Generic limits in Rhamnus L. s.l. Their showy fruit display and hardy foliage made them popular ornamentals and now highly competitive invaders of eastern woods and wetlands. The flowers are small, 3–5 mm (1⁄8–3⁄16 inch) in diameter, star-shaped with five greenish-white acute triangular petals, hermaphroditic, and insect-pollinated, flowering in May to June in clusters of two to ten in the leaf axils. All of these plants though, were credited with the power to protect against witchcraft, demons, poisons, and headaches. Invasive Species - (Rhamnus frangula or Frangula alnus) Glossy buckthorn is a shrub or small tree with simple, shiny leaves and pea-sized red to purple fruit. [3][23], Alder buckthorn charcoal is prized in the manufacture of gunpowder, being regarded as the best wood for the purpose. Identification. Catling, P.M., and Z.S. Frangula alnus, commonly known as alder buckthorn, glossy buckthorn, or breaking buckthorn, is a tall deciduous shrub in the family Rhamnaceae. Alder buckthorn is also taken as a tea. Glyphosate: Cut stump: Look for at least 25% active ingredient glyphosate for cut-stump treatments. The leaves are arranged alternately on 8–15-millimetre (5⁄16–19⁄32-inch) petioles. It was planted for hedgerows, forestry plantings, and wildlife habitat, but has become an invasive species, invading forests in the northeastern United States and wetlands and moist forest in the Midwestern United States. Leaves & stems: Ovate or elliptic, with prominent veins that come straight out from midrib and curve slightly towards the tip. Unlike other "buckthorns", alder buckthorn does not have thorns. They became a nuisance plant, forming dense thickets in ⦠But when Frangula alnus invades and grows in these locations, its dense canopy prevents light from reaching the ground and therefore prevents other seedlings from growing. It is also used as a tonic or as an ingredient in the Hoxsey cancer formula, but there is no good scientific evidence to support these uses. [13][14][15] It is predicted to continue to expand its North American range with time. It is native to Europe, northernmost Africa, and western Asia, from Ireland and Great Britain north to the 68th parallel in Scandinavia, east to central Siberia and Xinjiang in western China, and south to northern Morocco, Turkey, and the Alborz in Iran and Caucasus Mountains; in the northwest of its range (Ireland, Sc⦠The native Lance-leaved Buckthorn ( Rhamnus lanceolata ) is a smaller shrub (up to 6' tall) that also has toothed leaves and ⦠Flowers of buckthorn appear with the leaves in spring they are tiny, very inconspicuous, and light-medium green. For small populations of seedlings and small plants, hand pulling can be effective. Shelter belts and wildlife plantings are another reason it was planted. The history of invasion and current status of glossy buckthorn, World Checklist of Selected Plant Families. The flowers are valuable for bees, and the fruit an important food source for birds, particularly thrushes. [6][12][9], Frangula alnus is one of just two food plants (the other being Rhamnus cathartica) used by the common brimstone butterfly (Gonepteryx rhamni). They became a nuisance plant, forming ⦠[23], Species of flowering plant in the family Rhamnaceae, "Alder buckthorn" redirects here. But this woody plant escaped from yards and landscaped areas long ago, invading forests, oak savannas and other natural areas. [8], Frangula alnus was probably introduced to North America about 200 years ago, and in Canada about 100 years ago. With shiny leaves and small dark fruit, glossy buckthorn (Frangula alnus) grows as a deciduous shrub or a small tree up to 20 feet tall. [10] Although much disputed historically, the separation of Frangula from Rhamnus is now widely accepted, being supported by recent genetic data[11] though a few authorities still retain the genus within Rhamnus (e.g. It was not widely disseminated in the nursery trade in Minnesota until the mid to late 70s. Alder buckthorn has been used medicinally as a gentle laxative since at least the middle Ages. The bark yields a yellow dye, and the unripe berries furnish a green dye. Since its introduction, it has spread aggressively across most of the northeast and upper Midwest and has become a serious threat to the degra⦠[12][8] Other recorded names include glossy buckthorn and breaking buckthorn; historically, it was sometimes called "dogwood" through confusion of the leaves with those of dogwood Cornus sanguinea. Glossy buckthorn is shade-tolerant. It was introduced to North America in the 1880s as an ornamental shrub and was widely planted for fencerows and windbreaks in agricultural fields. (7) Shade/sun tolerance. This species produces leaves early in the spring and keeps its leaves late into the fall. Rhamnus frangula) are two small trees introduced from Europe and East Asia, respectively. The drug prepared from its bark is now more commonly employed than those prepared from the two previously described species. This species was introduced to North America as an ornamental shrub and used for living fence rows and wildlife habitat. Alder buckthorn may also refer to. tall hedge buckthorn . The species was used primarily in hedge plantings because it shears nicely. [17], It invades forests and grows in the understory in spots with a lot of light. Popular cultivars of it had narrow, columnar forms or fine feathery foliage with names like Tallhedge Buckthorn and Fernleaf Buckthorn. While buckthorns have long, very sharp spikes that can be extremely painful, chokeberry bushes are thornless. It produces many fruits, which are spread by birds, and invades fields, field edges, woodlands and wetlands, crowding out other plants. Take only the amount of bark needed to produce a soft stool. The Californian Buckthorn (Rhamnus purshianus), known more commonly as Cascara Sagrada, is a nearly-allied shrub growing in the United States, from northern Idaho westward to the Pacific Ocean. Once used for landscaping, this tree has now become an invasive species. glossy buckthorn . These buckthorn species were first brought here from Europe as a popular hedging material. Mass Audubon is a nonprofit, tax-exempt charitable organization (tax identification number 04-2104702) under Section 501(c)(3) of the Internal Revenue Code. The name of these species originates from the habit of their young branches to break off an⦠Alder buckthorn is a non-spiny deciduous shrub, growing to 3–6 m (10–20 ft), occasionally to 7 m (23 ft) tall. Buckthorn (Rhamnus frangula). These areas, usually where a tree has fallen, normally allow locally native tree seedlings to grow and eventually fill in the gap in the canopy. Common buckthorn, the most widely-found variety, has glossy green leaves with noticeable leaf veins. The shoots are dark brown, the winter buds without bud scales, protected only by the densely hairy outer leaves. Buckthorn Common, or European, buckthorn, and glossy buckthorn are the two non-native, invasive buckthorn species found in Minnesota. [18], Small saplings can be hand-pulled, but control of larger examples is best achieved using herbicides. 2000). It is often multi-stemmed. With shiny leaves and small dark fruit, glossy buckthorn (Frangula alnus) grows as a deciduous shrub or a small tree up to 20 feet tall. It was widely recommended for conserva- tion plantings in the Midwest until its invasive tendencies became apparent; it creates dense thickets and out-com- petes native vegetation. Unlike other "buckthorns", alder buckthorn does not have thorns. Anyone planning control work in these areas should first check with the local conservation commission; only herbicides registered for use in wetlands should be applied.

Hemlock-oak stands, which tend to be older stands of trees, are much less suitable for Frangula alnus because the density of the tree canopy creates a more shady environment that is not as suitable for Frangula alnus. It is most often found in woodlands and open fields, where it f⦠Porebski. Common buckthorn, native to Europe and Asia, is a highly invasive perennial understory shrub or a small tree that can reach heights of 20- 30 feet and 10 inches in diameter. [22], Alder buckthorn has limited decorative qualities without conspicuous flowers or bold foliage, and is mainly grown for its conservation value, particularly to attract Brimstone butterflies. [13] Its invasiveness is assisted by its high adaptability and pollution tolerance. This species was introduced to North America as an ornamental shrub and used for living fence rows and wildlife habitat. For larger plants, cutting can work well; either immediately apply a systemic herbicide to the cut stems, or apply it as a foliar spray to stump sprouts the following year. Glossy buckthorn was imported from Europe in the early 1900s as a landscape shrub. Both the common name alder buckthorn and specific epithet alnus refer to its association with alders (Alnus) on damp sites. Resource managers in the The species arrived in Minnesota from Europe in the 1850âs and was planted as an ornamental plant typically used in hedges. If using Roundup Concentrate you can mix 1 part water with 1 part herbicide to achieve a 50% solution. There are 8-9 pair of veins and the leaves are larger than the common buckthorn leaves. This trait allows glossy buckthorn to produce more carbohydrate and other compounds in the leaves by way of photosynthesis and transport these products to the roots for storage (i.e. Identification: Glossy buckthorn is an upright, spreading shrub or small tree that grows up to 23â tall. The leaves, flowers, seeds, and fruits are used to make medicine. https://www.fs.fed.us/database/feis/plants/shrub/fraaln/all.html Compared to Glossy Buckthorn, Common Buckthorn differs by having toothed leaves and its leaves have fewer lateral veins (typically 2-3 pairs). Buckthorn leaves are often glossy and a bit more rounded. Common buckthorn can thrive in a wide range of soil and light conditions, enabling it to invade a variety of habitats. Though members of the species are usually close in width and height, certain cultivated varieties are narrow and columnar in shape. Glossy buckthorn leaves are oval with a shiny upper surface, and toothless edges. Overview Information Sea buckthorn is a plant. [23], Galen, a Greek physician of the 2nd century A.D., knew of alder buckthorn, although he did not distinguish clearly in his writings between it and other closely related species. Inner bark is cathartic, cholagogue, laxative (the fresh bark is violently purgative), tonic, vermifuge. Donations to Mass Audubon are tax-deductible to the full extent provided by law. The fruit is a small black berry 6–10 mm (1⁄4–13⁄32 inch) in diameter, ripening from green through red in late summer to dark purple or black in early autumn, containing two or three pale brown 5-millimetre (3⁄16-inch) seeds. Glossy buckthorn. Common Buckthorn is non-native, originally brought to North America from Europe as an ornamental shrub. Common, or European, buckthorn, and glossy buckthorn are the two non-native, invasive buckthorn species found in Minnesota. European buckthorn (also called "common buckthorn" or just "buckthorn") is a tall, understory shrub brought to North America in the early 1800s as an ornamental shrub, primarily to serve as hedges. The recommendation for glossy buckthorn was based upon this literature review [PDF] developed by the department. The leaves are arranged on the branches in an alternate pattern. They are ovate, 3–7 cm (1 1⁄4–2 3⁄4 in) long by 2.5–4 cm (1–1 5⁄8 in) wide (rarely to 11 cm or 4 1⁄4 in by 6 cm or 2 1⁄4 in). It was subsequently separated by Philip Miller in 1768 into the genus Frangula on the basis of its hermaphrodite flowers with a five-parted corolla (in Rhamnus the flowers are dioecious and four-parted); this restored the treatment of pre-Linnaean authors, notably Tournefort. [21] It is considered invasive, but not banned, in Connecticut. It can grow as tall as seven metres. They have 6–10 pairs of prominently grooved and slightly downy veins and an entire margin. (Rhamnaceae) inferred from nuclear and chloroplast DNA sequence phylogenies. Comments: The strength numbers and mechanical data cited above is for Cascara Buckthorn (Rhamnus purshiana), while the foliage illustration, wood scans, and written descriptions are for Common Buckthorn ⦠The genus name Frangula, from Latin frango "to break", refers to the brittle wood. [16] It tends to grow more densely and with larger individuals in lower topographical areas with moist, fertile soils, and is very problematic for land managers. Always read and follow the directions on the label when using herbicide. However the buckthorn berries and not a good food source for our wild life species. Bark for medicinal use is dried and stored for a year before use, as fresh bark is violently purgative; even dried bark can be dangerous if taken in excess. cold weather storage for better winter survival and spring growth). Glossy buckthorn is also one of the first species to invade a forested site where tree and shrub layers have been removed or altered allowing gr eater levels of light to penetrate to the forest floor. Both species have naturalized throughout the United States, particularly the lake states and the Northeast. This plant frequently grows in wetlands subject to the Massachusetts Wetlands Protection Act. Its trunk is gray and smooth when young, ⦠Glossy buckthorn (Frangula alnus), an invasive shrub from Eurasia, colonizes both upland and mesic areas in northeastern North America but thrives particularly well along river, pond and wetland margins (Reinartz & Kline 1988; Catling & Porebski 1994; Possessky et al.
