Oregon, USA. Himalayan Blackberry (Rubus armeniacus Focke; synonyms: R. discolor, R. procerus) Rose family (Rosaceae) Himalayan blackberry was introduced into the U.S. in the late 1800s for cultivation and has since naturalized and spread out beyond planted areas. R. armeniacus is present in parts of Eurasia and is considered as native only to Armenia and possibly also northern Iran. CABI Bioscience Switzerland Centre report to the Swiss Agency for Environment, Forests and Landscape. Flowers: Blackberry flowers are white to pinkish, and consist of 5 stalked petals.They are approximately 2.5cm in diameter, and flowers are arranged in clusters of 5 to 20. Animals and birds eat the fruit and seed, thereby contributing to both long and short distance dispersal, depending on the animals’ range. Botanical Name: Rubus fruticosus. www.cal-ipc.org.

The vigorous vines grow 25 feet or more in a single season, swallowing fences and creek beds and filling abandoned lots with thick, thorny thickets that locals tramp through every August and September in pursuit of berries. Not only does this species propagate from root fragments, stem cuttings, and adventitious buds, but it also sets root and forms daughter plants where its rambling stems touch the ground, resulting in virtual cloning. The specie can outcompete many native North American species and degrades natural ecosystems. "It can grow in dry soils, wet soils," Shaw says.

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. For example, R. discolor has been incorrectly declared a weed or noxious weed in a number of states in the USA (USDA-ARS, 2015) and numerous academic publications refer to the three Rubus species as synonyms (e.g. Oregon, USA: Oregon State University. Salem, Oregon, USA: Oregon Deparment of Agriculture. Oregon lists Himalayan blackberry as a noxious weed, and the California Invasive In 1835 it was introduced to Germany by Booth, who named it R. fruticosus fr. It is native to Armenia and Northern Iran, and widely naturalised elsewhere. Although timing of application tends to vary between herbicides. The most commonly used herbicides include glyphosate, dicamba, dicamba/2,4-D combinations and triclopyr, metsulfuron and picloram (Soll, 2004; DiTomaso, 2010). Mature plants can reach 15 feet in height. Young plants grow over the dead canes, producing a tangled thicket than can be hard to remove.

A study from Oregon suggests that without control of R. armeniacus and other invasive species present in riparian ecosystems, the overall biodiversity of these areas could be adversely affected (Fierke and Kauffman, 2006). Data Source. The dense thickets can limit movement of large animals, for example, stopping them from reaching water and foraging areas (Soll, 2004). Leaves are toothed and typically compounded with five leaflets but atypically or on fruiting branches can be tri- or unifoliate. (ID# 11292). In North America, especially during the winter months, deer (Cervidae family), elk (Cervus canadensis), rabbits (Leporidae family), porcupines (Erethizontidae species), beavers (Castor species) and mountain beavers (Aplodontia rufa) have been reported to consume leaves, buds, twigs and the cambium (Klein, 2011; Francis, 2014).

In the USA and Canada, the species has also been reported to host the rust causing fungus Phragmidium violaceum, which has caused severe economic loss to commercially grown blackberries during the 2005 season in Oregon (Johnson and Mahaffee, 2010). A number of animals also rely on the thickets for shelter. This species is highly invasive and can form impenetrable thickets which have a negative impact on native flora and fauna. Seeds germinate in spring and once seedlings are established much of the subsequent reproduction is vegetative.

The species has been known to interfere with agriculture and forestry activities and has been reported to be a vector of the bacterial pathogen, Xylella fastidiosa, which causes Pierce’s disease in grapevines (Ensley, 2015). An explanation for this confusion is that R. armeniacus has been mistaken for R. praecox and thus confused for R. procerus (Jones, 2004). Haveman R; Ronde Ide; Bijlsma RJ; Schaminée J, 2014.
