County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Flower stalks are prickly, with robust stems (canes) that support large, flattened and hooked or straight prickles. This pathogen and also affects buds, unripe fruit and growing parts of the cane (Peters, 2012). Roots can sprout at the tips and both root and cane cuttings can establish new plants. The Rubus flora of the island of Amrum (Northern Germany). After Antarctica and Arctic, the Himalayan ranges is the home to third-largest deposit of snow and ice on this planet. Sweet, succulent blackberries are summer delicacies in the northern temperate regions. Ingestion by birds or mammals and long warm periods followed by long cold periods aid germination. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. DiTomaso JM, 2010. Many publications also use the common name Himalayan blackberry when referring to both R. discolor and R. armeniacus. http://wiki.bugwood.org/Rubus_armeniacus, Calflora, 2016.

It may not be permissible to grow the plant in the region and people may be required to remove it if it seeds naturally. The “berries” of Rubus plants are not berries in a botanical sense. Shaw says the Himalayan blackberry erodes soil and crowds out native plants and animals. 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. Like many Rubus species, R. armeniacus has been intentionally introduced into a number of countries for its production of fruit. Seed dispersal is also assisted by gravity. The dense thickets can limit movement of large animals, for example, stopping them from reaching water and foraging areas (Soll, 2004). But invasive species is also famous for its delicious blackberries. In 2005 a rust fungus, Phragmidium violaceum, infecting R. armeniacus was reported in Oregon, USA. Spontaneous hybrids between native and exotic Rubus in the Western United States produce offspring both by apomixis and by sexual recombination. http://www.fs.fed.us/global/iitf/pdf/shrubs/Rubus%20discolor.pdf, Hammer K, Cifarelli S, Perrino P, Laghetti G, 2004.

Watch Queue Queue Burning does not prevent re-sprouting from the root crowns either and has been reported to provide good conditions for seedling germination (Ensley, 2015). (Die Rubus-Flora der Nordfriesischen Insel Amrum.) This has been confirmed for New Zealand, however, its presence in Australia and South Africa is contested due to taxonomic confusion. The species tolerates occasional flooding with both fresh and brackish water. R. armeniacus prefers full sunlight but also grows well under light canopies. The rust fungus, Phragmidium violaceum, recently discovered on R. armeniacus in North America has triggered research into its potential as a biological control agent. Read more about these alternatives in the Grow Me Instead booklet for BC. When several references are cited, they may give conflicting information on the status. The latter is often recommended as a follow up strategy following manual removal. R. armeniacus has been cultivated along fences and trellises to create impenetrable barriers (Francis, 2014). Vegetative reproduction, where the canes take root via the tips has been reported to result in dispersal distances of up to 3 m from the parent plant (Ensley, 2015). The fact that Himalayan balsam is so attractive to bees reduces the insects' visits to native plants. However, in wetlands, cutting to ground level has proven effective as without the supporting canes, roots are reportedly unable to survive in anaerobic conditions (Soll, 2004). Himalayan blackberry has petite, white or faint pink flowers with 5 petals, arranged in clusters of 5-20. The most commonly used herbicides include glyphosate, dicamba, dicamba/2,4-D combinations and triclopyr, metsulfuron and picloram (Soll, 2004; DiTomaso, 2010). The seed coat is impermeable and the embryo remains dormant until it breaks (Ensley, 2015). Environmental Science and Management Faculty Publications and Presentations Paper 61. HortScience, 30(7):1447-1452. R. armeniacus is often found along waterways suggesting that natural dispersal of the seeds along waterways is common. Baton Rouge, USA: National Plant Data Center.

The mean annual rainfall for its distribution is 760 mm, however, in drier climates it is confined to riparian zones or alongside artificial waterways (Francis, 2014). Davis, California, USA: Weed Research and Information Center, University of California, 544 pp. It can be difficult to distinguish between species in the R. fruticosus aggregate, of which R. armeniacus belongs. They can quickly grow up to 15 feet tall and 40 feet long, outcompeting many other plants and forming dense monocultures. Interesting Himalayas Facts: 6-10. Fierke MK; Kauffman JB, 2006.
