The Info List - Rubus Chamaemorus

--- Advertisement ---

chamaemorus is a rhizomatous herb native to cool temperate, alpine, arctic tundra and boreal forest,[1] producing amber-colored edible fruit similar to the raspberry or blackberry. English common names include cloudberry,[2] bakeapple (in Newfoundland and Labrador), knotberry and knoutberry (in England), aqpik or low-bush salmonberry (in Alaska
– not to be confused with true salmonberry, Rubus spectabilis),[3] and averin or evron (in Scotland).

Male flower

Unlike most Rubus
species, the cloudberry is dioecious, and fruit production by a female plant requires pollination from a male plant.[1] The cloudberry grows to 10–25 cm (4–10 in) high.[1] The leaves alternate between having 5 and 7 soft, handlike lobes on straight, branchless stalks. After pollination, the white (sometimes reddish-tipped) flowers form raspberry-sized aggregate fruits which are more plentiful in wooded rather than sun-exposed habitats.[1] Consisting of between 5 and 25 drupelets, each fruit is initially pale red, ripening into an amber color in early autumn.

Cloudberries are a circumpolar boreal plant, occurring naturally throughout the Northern Hemisphere
Northern Hemisphere
from 78°N, south to about 55°N, and are scattered south to 44°N mainly in mountainous areas and moorlands.[1] In Europe, they grow in the Nordic countries, Baltic states and particularly in Poland.[1] They occur across northern Russia
east towards the Pacific Ocean
Pacific Ocean
as far south as Japan.[1] Due to peatland drainage and peat exploitation, they are considered endangered[1] and are under legal protection in Germany's Weser
and Elbe
valleys, and at isolated sites in the English Pennines
and Scottish Highlands. A single, fragile site exists in the Sperrin Mountains of Northern Ireland.[4] In North America, cloudberries grow wild across Greenland, most of northern Canada, Alaska, northern Minnesota, New Hampshire, Maine
and New York.[1][5] Wide distribution occurs due to the excretion of the indigestible seeds by birds and mammals. Further distribution arises through its rhizomes which are up to 10 m long and grow about 10–15 cm below the soil surface, developing extensive and dense berry patches.[1] Cuttings of these taken in May or August are successful in producing a genetic clone of the parent plant.[6] The cloudberry grows in bogs, marshes. wet meadows, tundra and altitudes of 1,400 metres (4,600 ft) above sea level in Norway, requiring acidic ground (between 3.5 and 5 pH).[1] Cloudberry leaves are food for caterpillars of several Lepidoptera species. The moth Coleophora thulea has no other known food plants. See also List of Lepidoptera
that feed on Rubus. Cultivation[edit]

Ripe cloudberries

Despite great demand as a delicacy (particularly in Sweden, Norway
and Finland) the cloudberry is not widely cultivated and is primarily a wild plant. Wholesale prices vary widely based on the size of the yearly harvest, but cloudberries have gone for as much as €10/kg (in 2004).[7] Since the middle of the 1990s, however, the species has formed part of a multinational research project. The Norwegian government, in cooperation with Finnish, Swedish and Scottish counterparts,[citation needed] has vigorously pursued the aim of enabling commercial production of various wild berries ( Norway
imports 200 - 300 tonnes of cloudberries per year from Finland). Beginning in 2002, selected cultivars have been available to farmers, notably "Apolto" (male), "Fjellgull" (female) and "Fjordgull" (female). The cloudberry can be cultivated in Arctic
areas where few other crops are possible, for example along the northern coast of Norway. Uses[edit]

Unripe cloudberry

Cloudberry jam

The ripe fruits are golden-yellow, soft and juicy, and are rich in vitamin C.[1] When eaten fresh, cloudberries have a distinctive tart taste. When over-ripe, they have a creamy texture somewhat like yogurt and a sweetened flavor. They are often made into jams, juices, tarts, and liqueurs. In Finland, the berries are eaten with heated "leipäjuusto" (a local cheese; the name translates to "bread-cheese"), as well as cream and sugar. In Sweden, cloudberries (sv. hjortron) and cloudberry jam are used as a topping for ice cream, pancakes, and waffles. In Norway, they are often mixed with whipped cream and sugar to be served as a dessert called "Multekrem" (cloudberry cream), as a jam or as an ingredient in homemade ice cream. Cloudberry yoghurt—molte-/multeyoughurt—is a supermarket item in Norway.[8] In Newfoundland and Labrador, Canada, cloudberries are used to make "bakeapple pie" or jam. Arctic
Yup'ik mix the berries with seal oil, reindeer or caribou fat (which is diced and made fluffy with seal oil) and sugar to make " Eskimo
ice cream" or Akutaq.[1] The recipes vary by region. Along the Yukon and Kuskokwim River
Kuskokwim River
areas, white fish (pike) along with shortening and sugar are used. The berries are an important traditional food resource for the Yup'ik. Due to its high vitamin C content,[1] the berry is valued both by Nordic seafarers and Northern indigenous peoples. Its polyphenol content, including flavonoid compounds such as ellagic acid, appears to naturally preserve food preparations of the berries.[1] Cloudberries can be preserved in their own juice without added sugar, if stored cool.[9] Alcoholic drinks[edit] In Nordic countries, traditional liqueurs such as Lakkalikööri (Finland) are made of cloudberry, having a strong taste and high sugar content. Cloudberry is used as a flavouring for making akvavit. In northeastern Quebec, a cloudberry liqueur known as chicoutai (aboriginal name) is made.[10] Nutrients and phytochemicals[edit] Cloudberries are rich in vitamin C and ellagic acid,[1] citric acid, malic acid, α-tocopherol, anthocyanins and the provitamin A carotenoid, β-carotene in contents which differ across regions of Finland
due to sunlight exposure, rainfall or temperature.[11] The ellagitannins lambertianin C and sanguiin H-6 are also present.[12] Genotype
of cloudberry variants may also affect polyphenol composition, particularly for ellagitannins, sanguiin H-6, anthocyanins and quercetin.[13] Polyphenol
extracts from cloudberries have improved storage properties when microencapsulated using maltodextrin DE5-8.[14] At least 14 volatile compounds, including vanillin, account for the aroma of cloudberries.[15] Cultural references[edit] The cloudberry appears on the Finnish version of the 2 euro coin.[16] The name of the hill "Beinn nan Oighreag" in Breadalbane in the Scottish Highlands
Scottish Highlands
means "Hill of the Cloudberries" in Scottish Gaelic.[17] Harvesting on public property[edit] In some northern European countries such as Norway, a common use policy to non-wood forest products allows anyone to pick cloudberries on public property and eat them on location, but only local residents may transport them from that location and only ripe berries may be picked.[18][19][20] Since 1970 in Norway, while it has been illegal to pick unripe cloudberries, transporting ripe cloudberries from the harvest location is permitted in many counties.[18] References[edit]
