In an invasive weed survey of the relatively pristine Middle Fork Snoqualmie Valley, Himalayan and evergreen blackberry covered more area than all of the other invasive species combined. The leaves on first year shoots are 7–20 cm long, palmately compound with either three or more commonly five leaflets. The flowers are produced in late spring and early summer on panicles of 3–20 together on the tips of the second-year side shoots, each flower 2–2.5 cm diameter with five white or pale pink petals. Description Blackberry, is a perennial shrub in the family Rosaceae that is grown for its aggregate black fruit of the same name. The best practices for removal include digging up the rhizomes and connecting underground structures, and herbicides. The underside of the leaves is white. Common names are from state and federal lists. [9] It does well in riparian zones due to the abundance of other species in these areas, which allows it to go relatively unnoticed until it has had a chance to establish itself. The blackberry is an edible fruit produced by many species in the genus Rubus in the family Rosaceae, hybrids among these species within the subgenus Rubus, and hybrids between the subgenera Rubus and Idaeobatus.The taxonomy of the blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. The stem is stout, up to 2–3 cm diameter at the base, and green; it is polygonal (usually hexagonal) in cross-section, with fearsome thorns up to 1.5cm long forming along the ribs. While some canes stay more erect, … R. armeniacus is a perennial woody shrub in which individual canes can reach 6-12 m horizontally and 3 m vertically. It is common in the Pacific Make sure to have a long-term plan to ensure success, protect native and beneficial species while doing the control, and start in the least infested areas first and then move into the more heavily infested areas. IDENTIFIERS. Foliage The leaves of the prima cane (first year shoots) are 2.8-7.9 in. Himalayan blackberry is a tall semi-woody shrub, characterized by thorny stems and dark edible fruits.

The name blackberry is used to describe several species, including Rubus fruticosis (wild blackberry), Rubus ursinus and Rubus argutus, two species native to North America. This blackberry species also has furrowed, angled stems while others are typically round. Trailing blackberry (Rubus ursinus) is a native species of blackberry in Washington that is smaller, generally grows along the ground, has narrow prickly stems instead of stout, start-shaped or ridged canes, and has only three narrower leaflets instead of five rounded leaflets like Himalayan blackberry. Himalayan blackberry Description: The Himalayan blackberry is the largest and possibly most invasive, non-native variety of blackberries in the Paci¿c Northwest. The stems, called canes, grow upright at first, then cascade onto surrounding vegetation, forming large mounds or thickets of the blackberry. It has large, deep, woody root balls that sprout at nodes. Canes or stems are biennial. The leaflets occur in groups of three or five and each resembles a large rose leaf. It grows upright on open ground and will climb over and trail over other vegetation. Leaves are palmately compound and usually have five leaflets. Müll.) Since then, it has invaded large areas throughout the west coast. The other, evergreen blackberry (Rubus laciniatus) looks like Himalayan blackberry from far away, but up close you can ID it by its leaves: While Himalayan blackberry has large, toothed, rounded or oblong leaves that grow most often in groups of five, … Himalayan blackberry can be distinguished by its smaller flowers ( 2-3 cm across ), erect and archy stems, and its 3-5 oval leaflets with whitew hairs. Himalayan blackberry is a Class C noxious weed that is not selected for required control in King County. The shrubs appear as "great mounds or banks" (Bailey 1945), with … It is common in the mountains of North Carolina and occasionally found on the Piedmont and coastal parts of the state. The most labor friendly and cost-effective way to remove this plant in smaller-scale infestations is to cut it as close to the ground as possible and then apply a drop or two of a triclopyr-based herbicide to the cut. Description Himalayan blackberry (synonym: Armenian blackberry) is a vigorous, sprawling, vine-like evergreen shrub native to western Europe. Main canes up to 10 feet long with trailing canes reaching up to … Subordinate Taxa. The blame for the Himalayan blackberry has traditionally fallen on Luther Burbank, the famed plant wizard who created hybrid novelties like the plumcot (a plum-apricot hybrid) at his experimental nursery in Sebastopol, California. Rubus armeniacus soon escaped from cultivation and has become an invasive species in most of the temperate world. Blackberry can be controlled with herbicides, but product labels should be followed carefully - different products need to be used at different times and may pose different risks to the user and the environment. Both its scientific name and origin have been the subject of much confusion, with much of the literature referring to it as either Rubus procerus or Rubus discolor, and often mistakenly citing its origin as western European. The canes of Himalayan blackberry can reach lengths of 40 feet and are typically green to deep red in color. Latin Names: Rubus armeniacus Rubus discolor Rubus procerus.

Both its scientific name and origin have been the subject of much confusion, with much of the literature referring to it as either Rubus procerus or Rubus discolor, and often mistakenly citing its origin as western European. Himalayan blackberry out-competes native understory vegetation and prevents the establishment of native trees that require sun for germination such as Pacific Madrone, Douglas Fir and Western White Pine. Although control of Himalayan blackberry is not required, it is recommended in protected wilderness areas and in natural lands that are being restored to native vegetation because of the invasiveness of these species. Mature plants form a tangle of dense arching stems, the branches rooting from the node tip when they reach the ground. Native to Eurasia; among the many native blackberries and raspberries, one can differentiate Himalayan blackberry by the five leaflets and curved spines with wide bases.

In its first year a new stem grows vigorously to its full length of 4–10 m, trailing along the ground or arching up to 4 m high. Himalayan blackberry is abundant along rivers and wetland edges in King County, often blocking access to these areas. Due to the threats the plant poses and its limited known distributions on O’ahu, OISC is working on eradicating Himalayan blackberry island-wide. This species spreads aggressively and has severe negative impacts to native plants, wildlife and livestock. For more information on noxious weed regulations and definitions, see Noxious weed lists and laws. This plant has no children. Dense, impenetrable blackberry thickets can block access of larger wildlife to water and other resources (not to mention causing problems for people trying to enjoy parks and natural areas). Because Himalayan blackberry is so widespread, property owners are not required to control it and we are not generally tracking infestations. There are tens of thousands of blackberry hybrids and segregates of various types, the thornless blackberry being a modern development. Riversides covered with blackberry often indicate degraded conditions and may mask eroding banks. Consider replanting the area with native plants well-suited to our local climate and soil conditions that will also provide benefits to our local ecosystems. The leaflets are moderately serrated. Himalayan blackberry is a thorny, thicket forming shrub in the Rose family that produces large, edible blackberry fruits. Overview Appearance Rubus armeniacus is a perennial shrub that is native to western Europe. It was first introduced from Europe to the area as a crop plant in the 1800’s. Himalayan blackberry out-competes native understory vegetation and prevents the establishment of native trees that require sun for germination such as Pacific Madrone, Douglas Fir and Western White Pine. Similarly, in EarthCorps' Seattle Urban Nature’s plant inventory of Seattle’s public forests, Himalayan and evergreen blackberry were found to be the most invasive species in Seattle's forests. Himalayan blackberry is a perennial bramblewith stems that grow up to 9 meters long. Himalayan blackberry is a Eurasian species introduced for fruit production that is highly invasive and difficult to control. Noxious Weed Information. Since then, it has invaded large areas throughout the west coast. Most King County offices will be closed on January 1, for New Year's Day. The flowers are bisexual (perfect) containing both male and female reproductive structures. In their second year, the shoots become smooth and produce flowering canes whose smaller leaves have 3 leaflets. Its leaves remain on the plant for a long period of time and sometimes persist all winter long in mild climates. It is native to Armenia and Northern Iran, and widely naturalised elsewhere. It is a notorious invasive species in many countries around the world and costs millions of dollars for both control and in estimated impacts. This is common in the summer. The cultivars "Himalayan Giant" and "Theodore Reimers" are particularly commonly planted. Mature plants can reach 15 feet in height. The shrub may reach up to 4 meters tall (Francis). Flowers are not produced on first year shoots. Evergreen blackberry (Rubus laciniatus) is another invasive, non-native blackberry that resembles Himalayan blackberry but has ragged looking leaves that are deeply lacerated or incised. [6], The fruit in botanical terminology is not a berry, but an aggregate fruit of numerous drupelets, 1.2–2 cm diameter, ripening black or dark purple. Flora of North America, published in 2014, c… Removal of top growth by mowing, cutting or grazing with goats will eventually kill blackberry if done regularly and over several years. It was valued for its fruit, similar to that of common blackberries (Rubus fruticosus and allies) but larger and sweeter, making it a more attractive species for both domestic and commercial fruit production. This plant is listed by the U.S. federal government or a state. [7], The species was introduced to Europe in 1835 and to Australia and North America in 1885. It grows upright on open ground, and will climb and trail over other vegetation. It was ¿rst introduced from Europe to the area as a crop plant in the 1800’s. Focke. Leaflets are large, broad, oblong, 6 ¼ to 13 cm Native blackberries also grow in this region, but they are a much rarer sight. [12] It is especially established West of the Cascades in the American Pacific Northwest. [8] Broken roots can resprout, making manual removal extra labor intensive, and glyphosate herbicides are largely ineffective with this plant. Himalayan Blackberry Description Himalayan blackberry (generally known scientifically as Rubus discolor, R. procerus or R. fruticosa, but technically R. armeniacus) is a robust, perennial, sprawling, more or less evergreen, shrub of the Rose family (Rosaceae). The canes can turn more red/purple if they are exposed to bright sunlight. Flowers are in flat-topped clusters of 5 to 20 flowers, each with 5 petals, white to light pink, about 1 inch in diameter. First-year canes develop from buds at or below the ground surface and bear only leaves. These leaflets are oval-acute, dark green above and pale to whitish below, with a toothed margin, and snaring, hooked thorns along the midrib on the underside. Himalayan blackberry and its close relative Evergreen blackberry (Rubus laciniatus) are native to Europe and were introduced to the U.S. for fruit production. Himalayan blackberry is abundant along rivers and wetland edges in King County, often blocking acces… In its second year, the stem does not grow longer, but produces several side shoots, which bear smaller leaves with three leaflets (rarely a single leaflet). Rubus armeniacus is an arching woody shrub. Description. Its leaves remain on the plant for a long period of time and sometimes persist all winter long in mild climates. Focke. We can provide advice on how to control blackberry, but there is generally no requirement to do so, unless the city or homeowners association requires it. Unlike other invasive species, this plant can easily establish itself and continue to spread in ecosystems that have not experienced a disturbance. Due to the deep roots, digging up large established plants is difficult and may need to be repeated if not all the roots are removed. The canes of Himalayan blackberry can reach lengths of 40 feet and are typically green to deep red in color. Rubus armeniacus, the Himalayan blackberry[1] or Armenian blackberry, is a species of Rubus in the blackberry group Rubus subgenus Rubus series Discolores (P.J. These thickets can oftentimes provide good nesting grounds for birds, and help to provide places to rest/hide for other slightly larger mammals, such as rabbits, squirrels, beavers, etc.[9]. What’s more, Himalayan blackberry isn’t the only invasive blackberry growing in our area — though it is the most common. All species of blackberry have edible fruits, but the fruits on the native trail blackberry are smaller (but tastier!). Stems live two or three years, frequently root at the tips, are very strongly angled rather than round, and have large, curved spines. Rubus armeniacus is a perennial plant that bears biennial stems ("canes") from the perennial root system. Mature plants can reach up to 15 feet in height. Both first and second year shoots are spiny, with short, stout, curved, sharp spines. The goal of this dissertation is to examine the effectiveness of high intensity-short duration goat browsing for the control of Himalayan blackberry (Rubus armeniacus) and English ivy (Hedera helix), two widespread noxious weeds in the Pacific Northwest. GENERAL BOTANICAL CHARACTERISTICS : The Himalayan blackberry is a robust, clambering or sprawling, evergreen shrub which grows up to 9.8 feet (3 m) in height [25,31].Leaves are pinnately to palmately compound, with three to five broad leaflets [25,31].Mature leaves are green and glaucous above but tomentose beneath [].Stems of most blackberries are biennial. [8], When established for several years, if left alone, Rubus armeniacus can grow into a large cluster of canes. It is native to Armenia and Northern Iran, and widely naturalised elsewhere. Blackcap ( Rubus leucodermis ) a less common native, can be distinguished by its paler green-blue erect stems, purple fruits, and leaves that have fine white hairs underneath. Legal Status. The canes of Himalayan blackberry can reach lengths of 40 feet and are typically green to deep red in color. It grows in many habitats, including the edge of forests, in open woodlands, beside trails and roads, in … [2][3] Rubus armeniacus was used in the cultivation of the Marionberry cultivar of blackberry. Blackberry can be controlled by digging, mowing, herbicide, plowing, and/or livestock grazing (especially goats). The immature fruits are smaller, red, and hard with a much more sour taste. [8] The shrub spreads through rhizomes underground, making it very difficult to remove. Müll.) Himalayan blackberry, like other invasive plants, reduces the environmental services provided by a healthy forested watershed. Its usual scientific name is Rubus armeniacus, but it's sometimes known as Rubus discolor. Repeated cutting can help keep the plants from overtaking over vegetation. Himalayan blackberry is a rambling evergreen, perennial, woody shrub with trailing, stout stems that possess sharp, stiff spines. [9] Cutting the canes to the ground, or burning thickets of Rubus armeniacus are ineffective removal strategies. Leaves are toothed and typically compounded with five leaflets but atypically or on fruiting branches can be tri- or unifoliate. Leaves are somewhat evergreen, divided into 3-5 leaflets (palmately compound) that are rounded (ovate) and have toothed edges. The leaves of the first year shoots are 3 to 8 in long and consist of 5 leaflets arranged like the fingers of a hand. [2][3][10][8][11] Because it is so hard to contain, it quickly gets out of control, with birds and other animals eating the fruit and then spreading the seeds. : Himalayan Blackberry is an arching woody shrub. In some areas, the plant is cultivated for its berries, but in many areas it is considered a noxious weed and an invasive species. Control is recommended but not required because it is widespread in King County. Description: The Himalayan blackberry is the largest and possibly most invasive, non-native variety of blackberries in the Pacific Northwest.
