In year 10, every second tree is sold or converted into high BTU wood pellets. Vineyard posts are usually 8 feet long and about 4.5 inches in diameter. [14] Exceptionally, it may grow up to 52 metres (171 ft) tall[15] and 1.6 metres (5.2 ft) diameter in very old trees. Native geographic location and habitat. Black locust has been spread and used as a plant for erosion control as it is fast growing and generally a tough tree. Although similar in general appearance to the honey locust, the black locust lacks that tree's characteristic long branched thorns on the trunk, having instead the pairs of short prickles at the base of each leaf; the leaflets are also much broader than honey locust. In the early summer black locust flowers; the flowers are large and appear in large, intensely fragrant clusters reminiscent of orange blossoms. Black locust trees are quite drought-tolerant once established and will grow in a wide variety of well-draining soil types. [14] This makes removal of black locust difficult as the suckers need to be continually removed from both the trunk and roots or the tree will regrow. All photographs and text ©2013 by Will Cook unless otherwise noted. Louisiana Plant ID is an online resource for images and descrptions of Louisiana plants and ecosystems. European governments are leading the way by blocking the importation of tropical wood, in an effort to curb log poaching and unsustainable harvesting. These trees have more deeply furrowed bark, branches that grow in zig zag patterns, … And so far, we have had less attack by insects and fungus compared to oak, walnut, persimmon, and pine. [7], Robinia is a native North American genus, but traces of it are found in the Eocene and Miocene rocks of Europe.[8]. [11] These ecosystems have been decreasing in size, and black locust is contributing to this reduction; when black locust invades an area, it will convert the grassland ecosystem into a forested ecosystem where the grasses are displaced. Black locust reproduces both sexually via flowers, and asexually via root suckers. On average, the thinned trees will increase two times diameter compared to a plantation without thinning. Although native to Eastern North America, Bthis tree grows in micro-climate areas of the Western States and Canada, principally the central interior of British Columbia, Canada and Washington State. Black Locust trees usually grow to between 12 to 30 meters high, or 40 to 100 feet high. The Black Locust (Robinia pseudoacacia) ranks among the 40 worst invasive tree species in the world. Ones that grow in competition, however, grow reasonably straight. Black locust is shade intolerant and does very well in disturbed areas. Whaddaya expect when it's practically the most durable and stable wood available? It also often spreads by underground shoots or suckers, which contributes to the weedy character of this species. It can grow up to 100 feet high. Transplants easily to any soil and climate even under the toughest conditions. I'd make everything out of it. A few months ago I nabbed a few boards and made a picture frame with an 8x10 photo of his mill inside. After a bad ice storm toppled a few, my father cut all but one for firewood (the rest cracked and split as they came down). Black locust blossoms produce such delicious honey that the trees where introduced to Europe about 40 years ago (however, it blooms only 10 days per year, making the honey rare as well as delicious). Old trees are commonly infected with the borer and some fungus diseases. A deciduous tree with short, irregular branches and feathery leaves, the black locust grows fast but is short-lived. Black locust is highly valued as firewood for wood-burning stoves; it burns slowly, with little visible flame or smoke, and has a higher heat content than any other species that grows widely in the Eastern United States, comparable to the heat content of anthracite. Some of these poles are still in use today; as sound as the day they were driven into the ground. In the prairie and savanna regions of the Midwest black locust can dominate and shade open habitats. In Romania the flowers are sometimes used to produce a sweet and perfumed jam. and planted them at my house some 65 miles away and they are growing great. Exceptionally, it may grow up to 52 metres (171 ft) tall and 1.6 metres (5.2 ft) diameter in very old trees. It has white flowers and compound leaves, and the saplings and smaller branches of mature trees have thorns. Although this tree will grow in shade, it may take 3 to 4 times longer to mature into a sizeable sawlog. Hard to work? However, its blooming period is short (about 10 days) and it does not consistently produce a honey crop year after year. This tree can sucker to the point of forming colonies. Woodpeckers may also nest in the trunk since older trees are often infected by heart rot. Black locust trees grow to between 40 and 100 ft. (12 – 30 m) with exceptional varieties reaching heights of 171 ft. (52 m). [4] Another common name is false acacia,[5] a literal translation of the specific name (pseudo meaning fake or false and acacia referring to the genus of plants with the same name). The wood is extremely hard, being one of the hardest woods in Northern America. "Purple Robe" black locust (Robinia pseudoacacia "Purple Robe") can grow in some of the most difficult conditions and on a variety of sites. It is the perfect wood for fence and deck posts. Horses that consume the plant show signs of anorexia, depression, incontinence, colic, weakness, and cardiac arrhythmia. [33] Important constituents of the plant are the toxalbumin robin, which loses its toxicity when heated, and robinin, a nontoxic glucoside.[34]. The black locust is native to the eastern United States, but the exact native range is not accurately known[9] as the tree has been cultivated and is currently found across the continent, in all the lower 48 states, eastern Canada, and British Columbia. [18] The seedlings grow rapidly but they have a thick seed coat which means that not all seeds will germinate. Black locust does not do well on compacted, clayey or eroded soils. When Black Locust posts, timber and poles became less plentiful, farmers would burn the lower end of each post, timber or pole over an open fire to seal the wood to prevent water penetration. That was 15 years ago. 'Purple robe' has dark rose-pink flowers and bronze red new growth. [9] This tree tolerates a soil pH range of 4.6 to 8.2. The sharp spines on black locusts are usually present on immature trees and grow at the base of each leaf. Because of their prolific growth, black locust trees are considered nuisance trees in many areas where they have escaped into the wild. Growing locust trees is easy and they adapt well to lawn and street conditions. There is an apartment complex near where I live with a huge grove of Black Locust trees. I’m a 75 year old (ouch) amateur cabinet maker and have just completed a desk using this wood, and before that a six foot long sideboard. Heart rot is the only significant disease affecting black locust. It is a very upright tree with a straight trunk and narrow crown that grows scraggly with age. The black locust is native from Pennsylvania to northern Georgia and westward as far as Arkansas and Oklahoma, but has been widely spread in other areas of the world. You might think that the name honey locust comes from the sweet nectar that bees use to make honey, but it actually refers to the sweet fruit that is a treat for many types of wildlife. The national champs: black locust i~100" DBH [7] Young trees are often spiny, but mature trees often lack spines. [7] The dark blue-green compound leaves with a contrasting lighter underside give this tree a beautiful appearance in the wind and contribute to its grace. We build turnkey Crop Circle Tree Plantation projects that reclaim land, combat climate change, create carbon credits, initiate habitat renewal, build legacy forests and stable long-term timber investment. Black Locust can be a really fast growing tree. I have taken a few sprigs from the ground (they seem to spread like weeds!) Black locust (Robinia pseudoacacia) is found throughout the United States in woodland areas and along stream banks. It's also very rot resistant and commonly used for fence posts and exterior construction on farms. Another is that it accelerates tree growth by as much as 20%. As a bandmill sawyer, last year I started sawing the wood, and what a surprise, it saws just as easy as cherry, and the grain and color is out of this world. Cultivars may also be grafted as this ensures the parent and daughter plant will be genetically identical. [14] On sandy soils black locust may also often replace other vegetation which cannot fix nitrogen.[17]. I sawed a couple hundred board feet the other day to use as a floor for a kiln, due to the moisture resistance. The extreme resistance to rotting is perhaps the black locust's best-known attribute, and it was on poles of black locust that the first buildings were erected. This is a huge opportunity for tree farmers living in temperate climatic zones. Black locust is resistant to black walnut toxicity. Black locust trees can reach heights of 70 to 80 feet but are more often 30 to 50 feet tall. Members of the pea family, locust trees produce large clusters of pea-like flowers that bloom in spring, followed by long pods. I have gotten it for only slightly more than the price of oak. Start your Black Locust tree plantation with ten foot tall black locust tree seedlings. [19] These soil nitrates are usable by other plants. Most natural reproduction is vegetative by means of root suckering and stump sprouting. The black locust bears toxic pods that hang from its branches, but it also has white, fragrant flowers that bloom in late spring. Black Ebony is a much-branched, many-stemmed, spiny, deciduous tree losing its foliage in the dry season, or shrub of dry woodland and … [7][17] The seeds are produced in good crops every year or every other year. Black Locust: Black locust trees (Robinia pseudoacacia), also known locally as “Chicago blues,” is a fast-growing tree that does not get quite as tall as the honey locust. In Europe, it is often planted along streets and in parks, especially in large cities, because it tolerates pollution well. Growing black locust trees is easy, but they can become weedy if you aren’t diligent about removing suckers. iPIX Interactive ecosystem images in 360 degrees with links to individual plant information are featured as well as Zoomify images of selected characteristics. Honey locust trees grow long, twisted pods. The flowers tend to last longer than on the wild tree. Technically, both the black and honey locust are considered medium sized trees...typically topping out ~2' DBH. Root suckers are an important method of local reproduction of this tree. I was fascinated by your blog on this tree, which I’m in love with. We need trees that can grow without alot of fuss. They have a diameter of between 0.60 to 1.2 meters ( 2- 4 feet). We have found at least 5 advantages for the lazy grower like myself. Since then it has made its way into gardens in Africa, Asia and Australia. It grows best in full sun with moderate moisture. Its importance as a non-toxic chemical free wood cannot be understated given the present state of the environment and water quality across the country. (231) 464-5809 The tree will seed itself in these old pastures and grow in fairly dense stands that are very straight and tall (sometimes over 100 feet). Boggy soil that dries occasionallyit grows here too. [10], Black locust is an interesting example of how one plant species can be considered invasive even on the continent to which it is native. [22] In fireplaces, it can be less satisfactory because knots and beetle damage make the wood prone to "spitting" coals for distances of up to several feet. It crowds out native vegetation of prairies, oak savannas and upland forests, forming single species stands. The leaves are pinnately compound on older trees but bipinnately compound on vigorous young trees. It prefers dry to moist limestone soils but will grow on most soils as long as they are not wet or poorly drained. In the Netherlands and some other parts of Europe, black locust is one of the most rot-resistant local trees, and projects have started to limit the use of tropical wood by promoting this tree and creating plantations. The following comments where collected from a national wood products discussion forum. Black locust leaves contain flavone glycosides characterised by spectroscopic and chemical methods as the 7-O-β-d-glucuronopyranosyl-(1 → 2)[α-l-rhamnopyranosyl-(1 → 6)]-β-d-glucopyranosides of acacetin (5,7-dihydroxy-4′-methoxyflavone), apigenin (5,7,4′-trihydroxyflavone), diosmetin (5,7,3′-trihydroxy-4′-methoxyflavone) and luteolin (5,7,3′,4′-tetrahydroxyflavone). ( In late May/early June the perfume is amazing. With fertilizer prices rising, the importance of black locust as a nitrogen-fixing species is also important. They are incredibly hard-lived trees that have the great ability to tolerate compacted soils, wind storms, ice, salt, pollution, and foot traffic. [9] It specializes in colonizing disturbed areas and edges of woodlots before it is eventually replaced with taller or more shade-tolerant species. The dark blue-green compound leaves with a contrasting lighter underside give this tree a beautiful appearance in the wind and contribute to its grace. About Purple Robe Trees. [17] The locust borer Megacyllene robiniae larvae carve tunnels into the trunk of the tree and make it more prone to being knocked down by the wind. By using the existing root system to grow new tree shoots, a Black Locust tree plantation becomes a sustainable resource for a variety of wood products including structural timber, hardwood florring, fence posts, ground contact landscape timber, split rail fencing and wood pellets. My parents have several dozen large trees on their property. The finished product was better than I could imagine. Black locust trees (Robinia pseudoacacia, USDA zones 4 through 8) are at their best in late spring, when trailing clusters of 5-inch, fragrant flowers bloom at the tips on new branches.The flowers attract honeybees, which use the nectar to make excellent honey. Black Locust native growing areas are concentrated in the Eastern United States, with the highest concentration in the state of Ohio. In late May/early June the perfume is amazing. The tree grows on a variety of sites ranging from moist slopes to dry soils, preferring sandy or rocky soil. Although the EPA has restricted the use of these chemicals for residential use, CCA is still used heavily by the industrial and agricultural sectors. It is a commonly held belief that fast-growing trees have weak wood and invasive roots, however, honey locust trees do not fall in that category. It is absolutely fabulous wood to work with and to look at when finished. Locust leaf miner Odontota dorsalis attacks the tree in spring and turns the leaves brown by mid summer, it slows the growth of the tree but not seriously. Black Locust is armed with two spines at the base of each leaf or leaf bud. Posts made of this wood are good for grapevine supports in vineyards. Although the bark and leaves are toxic, various reports suggest that the seeds and the young pods of the black locust are edible. Black locust's current range has been expanded by humans distributing the tree for landscaping and now includes Pakistan, India, Australia, Canada, China, Europe, Northern and South Africa, temperate regions in Asia, New Zealand, Southern South America. It was introduced into Britain in 1636. For example, within the western United States, New England region, northern California, and in the Midwest, black locust is considered an invasive species. Often forms dense stands where established and can choke out other vegetation. It doesn’t last near as long as Black Locust wood in the ground but it is environmentally safe. Plus it smells good in the Spring. The wood is weak and brittle, subject to storm damage. 'Unifoliola', a plant with fewer leaflets, no prickles, and a shorter height. In many European countries, it is the source of the renowned acacia honey. Black Locust can be a really fast growing tree. He dragged it to his sawmill across the road in the spring and sawed some dimensional lumber from it and placed the lumber in his basement. The entire Province/State is coloured, regardless of where in that Province/State it occurs. I live in (West) Vancouver BC , and in a huge windstorm in 2006, this tree was blown down. Several cultivars exist but 'Frisia' seems to be one of the most planted ones. Black locust is a prolific seed producer, but seedlings are not common; few seeds germinate because of the impermeable seed coat. Black Locust wood contains natural organic compounds that resist rot for 100 years or more, which makes these trees an extremely valuable and environmentally friendly tree. It is found in old fields, open areas, streamsides, woods, and along roadsides and fencerows. It is endemic to a few small areas of the United States, but it has been widely planted and naturalized elsewhere in temperate North America, Europe, Southern Africa[3] and Asia and is considered an invasive species in some areas. Native to eastern and southern parts of the United States. In the days of a changing world, we need allies like black locust. It can be easily propagated from roots, softwood, or hardwood[7][17] and this allows for easy reproduction of the plant. It has a very low rate of expansion and contraction, making it very stable for furniture and woodwork (interior or exterior). Haywood Co., NC 5/10/08. The green and yellow hues were beautiful. Black Locust plantations cost around $5,000 per acre (based on a $25 price for each 10 foot tall tree sapling) depending on how many acres are planted for any given project – the more acres the lower the cost. An average 200 trees per acre is common. It still works today, although the fire has been replaced with a blowtorch. Black locust trees will continue to produce seeds until they reach age 60. Its seeds are also eaten by bobwhite quail and other game birds and squirrels. [8], In traditional medicine of India, different parts of R. pseudoacacia are used as laxative, antispasmodic, and diuretic.[28]. This means manual harvesting of flowers, eliminating the seeds and boiling the petals with sugar, in certain proportions, to obtain a light sweet and delicate perfume jam. Black locust is a legume with root nodes that, along with bacteria, "fixes" atmospheric nitrogen into the soil. The main trunk also has the capability to grow sprouts and will do so after being cut down. R. pseudoacacia is considered an excellent plant for growing in highly disturbed areas as an erosion control plant. Trees, Shrubs, and Woody Vines of North Carolina. [6] Jesuit missionaries apparently fancied that this was the tree that supported St. John in the wilderness, but it is native only to North America. Black Locust tree seedlings grow rapidly, are highly resilient in a variety of soils, and grow back even faster from its stump after harvest. Shelled seeds are safe to harvest from summer through fall, and are edible both raw and/or boiled. Use sharper tools. [27] For best results, it should be seasoned like any other hardwood, but black locust is also popular because of its ability to burn even when wet. Flavonoids in the heartwood allow the wood to last over 100 years in soil.[26]. It has been planted in 48 states and was noted as spreading in jack pine barrens in Michigan as early as 1888. Locust is incredibly crooked in its “natural” form, and so seed selection, and sometimes pruning, is a critical factor for success. Apparently acacia, as many call it, was planted along the Fraser River as fuel for the paddle wheelers in the 19th Century, and is occasionally milled around here. The physical construction of the flower separates the male and female parts so that self-pollination will not typically occur. The black locust is commonly referred to as "false acacia" after its species name "pseudoacacia". While splitting the wood one can't help but notice a beautiful gold-green sheen to the heavy, straight veined splits. Such trees develop heart decay (fig. Carroll Co., VA 4/11/10. a medium-sized tree (up to 25 m or 80 ft tall) with long compound leaves belongs to the Pea family; like many other species in the Pea family, it has nitrogen-fixing bacteria in its roots enabling the tree to grow vigorously in poor soil Black Locust trees are singularly planted in a mono-cropped one-spiral plantation. It's a wonderful species for firewood – it burns hot and long if properly seasoned. I only wish there was a supply of this lumber in my area. Locusts are fast-growing, hardy trees that belong to the pea family Fabaceae or Leguminosae.Most of the locust species are classified into two genera – Gleditsia and Robinia.While the genus Gleditsia has 12 species, there are around ten species in the genus Robinia.The most popular among them are Robinia pseudoacacia (black locust) and Gleditsia triacanthos (honey locust). The tree was named for its resemblance to Ceratonia siliqua, known as the "Old World Locust". The flowers are pollinated by insects, primarily by Hymenopteran insects. In 1601 its first seeds were sent from the Americas to France. Weather conditions can have quite an effect on the amount of nectar collected, as well; in Ohio for example, good locust honey flow happens in one of five years.[21]. There is no need to use a waterseal. The roots may grow suckers after damage (by being hit with a lawn mower or otherwise damaged) or after no damage at all. The colors that came out in that wood after a semi-gloss varathane was applied were amazing. Partner with us and build a Black Locust Tree Plantation on your land, our land or anywhere in the world. Robinia pseudoacacia, commonly known in its native territory as black locust,[2] is a medium-sized hardwood deciduous tree, belonging to the tribe Robinieae. One is, it conserves water, requiring just half of an irrigated plantation. If the tree has room to grow, on a heavy watered site in full sun, it is possible to gain one full inch of radial growth in just 6 years. Third, that root regeneration insures reforestation even after harvest, mechanical damage, or fire. Black locust should be reported. Fast growing! The Problem. The wood was a bit boxy when ripped on the table saw and it planed up nice with my 15" Makita floor planer. [10] In South Africa, it is regarded as a weed because of its suckering habit.[13]. Most legumes have pea-like flowers with distinctive seed pods. Black Locust Trees are plants in the subfamily Faboideae of the pea family Fabaceae. Wet, newly cut planks have an offensive odor which disappears with seasoning. Black locust is a part of the Appalachian mixed mesophytic forests. The toxins leached from the pressure treated lumber in use over the past 50 years have done immeasurable damage to the environment. Black locust has nitrogen-fixing bacteria on its root system, so it can grow on poor soils and is an early colonizer of disturbed areas. Haywood Co., NC 5/10/08. (Range map provided courtesy of the USDA website and is displayed here in accordance with their Policies) There is a widespread habit of allowing black locust trees to grow beyond their age of maturity, which is often 20 to 30 years. Depending on market conditions, Black Locust tree plantations gross between $30,000 and $50,000 per acre in year 30 and double that in year 50. Black locust reaches a typical height of 40–100 feet (12–30 m) with a diameter of 2–4 feet (0.61–1.22 m). They are typically dog-legged. In some countries, Black Locust is being promoted as an alternative to tropical hardwoods; many of which are endangered. [17] Within its native range it will often grow on soils of Inceptisols, Ultisols, and Alfisols groups. It is considered an environmental weed there. It's hard to find a good straight black locust. Black locust has been found to have either 2n=20 or 2n=22 chromosomes. Some of the older ones were cut down by N.Y. State in its infinite wisdom, and I was able to take out about a cord and a half as firewood. I got most of the trunk and had it milled. Range map for Black Locust (Robinia pseudoacacia) PLEASE NOTE: A coloured Province or State means this species occurs somewhere in that Province/State. The wood is tougher than hickory, which is tougher than hard maple, which is tougher than oak. Black Locust (Robinia pseudoacacia L.) 5 Flowers: Fragrant clusters of 10 to 25 pea-like, white flowers hang from branches in late spring. [12] Black locust has been listed as invasive in Connecticut and Wisconsin, and prohibited in Massachusetts. Now all of that growth is on the ground in the form of millions of tiny lentil-like seeds. It is very resistant to rot, and durable, making it prized for furniture, flooring, paneling, fence posts, and small watercraft. Not only is it tough (second only to osage orange as the toughest native wood) and resistant to moisture (much better than white oak) and rot (way better than cedar), it is gorgeous! When growing in sandy areas this plant can enrich the soil by means of its nitrogen-fixing nodules, allowing other species to move in. Black locust is a nitrogen-fixing tree that prefers disturbed habitat, old fields, thickets and degraded woods. I gather it is also called false acacia. The tree was identified in 1607 at Jamestown by British colonists, who used the timber to build houses. A thinning program should be initiated during year 10, cutting every second tree for firewood or wood pellet production so the remaining trees will size up (increae diameter). Black locust is still in use in some rustic handrail systems. Although virtually forgotten, the benefits of the Black Locust tree and Black Locust wood are seemingly endless; long-life in the ground, bee-attracting flowers for honey production, the highest tensile beam strength of any American tree including Ironwood, ability to reclaim land and stabilize erosion-prone hillsides because of a rebar-like interlacing root system, improves soil by fixing plant loving nitrogen to its roots and one of the highest BTU (British Thermal Unit) – (Utah State University). 'Tortuosa', a small tree with curved and distorted branches. 17). Ample sunshine is essential to maximize growth and yield. The suckers allow black locust to grow into colonies which often exclude other species. Locust borer is a serious pest of black locust. That's why so many are made into fence post. In 1900, the value of Robinia pseudoacacia was reported to be practically destroyed in nearly all parts of the United States beyond the mountain forests which are its home by locust borers which riddle the trunk and branches. At least it used to before the beetle borers showed up. Black locust is a shade-intolerant species[9] and therefore is typical of young woodlands and disturbed areas where sunlight is plentiful and the soil is dry. The pods turn a deep brown in fall and are full of oval, brown seeds. I agree with others that Black Locust should really be promoted for all its potential uses. [22], Black locust is also planted for firewood because it grows rapidly, is highly resilient in a variety of soils, and it grows back rapidly from its stump after harvest by using the existing root system. The seed coat can be weakened via hot water, sulfuric acid, or be mechanically scarified, which will allow a greater quantity of the seeds to grow. The pulp inside the pods is edible, unlike the black locust, which is TOXIC. [31][circular reference][32], The bark, leaves, and wood are toxic to both humans and livestock. As the strongest timber in North America, these trees helped build early Colonial towns and hardened the navy (along with ironwood) that decided the War of 1812, yet today few Americans have heard of it. The mass application of fertilizers in agriculture and forestry is increasingly expensive; therefore nitrogen-fixing tree and shrub species are gaining importance in managed forestry. Locust wood is as hard as any I've ever worked with, and it is of the highest quality! Locust can also be used for fence posts. It can tolerate drought and poor-quality soil and can be found growing natively in … In fact, old telegraph lines still have their original poles sticking out of the ground 150 years later. Item # L1048 Shipping Size: 2-4 Feet - GROWING ZONES: 4-9 / SUN EXPOSURE: Full to partial Sun Images are provided in galleries and are available by common name, scientific name, family, ecosystem, and wetland indicator status. The leaflets fold together in wet weather and at night (nyctinasty), as some change of position at night is a habit of the entire leguminous family. These colonies may form dense thickets which shade out competition. It is a very upright tree with a straight trunk and narrow crown that grows scraggly with age. [17] Black locust is also attacked by Chlorogenus robiniae, a virus which causes witch's broom growths, clear leaflet veins are a symptom of the disease. In this sense, black locust can often grow as a weed tree. The leaflets are 1.5–2.5 cm (0.6–1 in) (smaller on bipinnate leaves) and bright green. Dry sandy soilno problem. I am a wood-flooring contractor and have installed a couple Black Locust floors. It may also resemble Styphnolobium japonicum, which has smaller flower spikes and lacks spines. Biology. Robinia pseudoacacia 'Allegheny' - Grows To 50', Upright tree, will develop thickets. Looking for a faster return on investment? [17] The wood, considered the most durable wood in North America, has been very desirable and motivated people to move the tree to areas where it is not native so the wood can be farmed and used. The black locust is a plant from the subfamily of Faboideae in the family of legumes (Fabaceae) and is a relative of the pea and bean. Compacted soil in an urban areano problem. [17] The shallow, aggressive roots help hold onto the soil; the tree grows quickly and on poor soils due to its ability to fix nitrogen.
2020 where do black locust trees grow
