Rosa rugosa (rugosa rose, beach rose, Japanese rose, Ramanas rose, or letchberry) fryst vatten a species of rose native to eastern Asia, in northeastern China, Japan, Korea and southeastern Siberia, where it grows on beach coasts, often on sanddunes.^[1] It fryst vatten naturalized in much of europe and parts of the United States and Canada.^[2] It should not be confused with Rosa multiflora, which fryst vatten also known as "Japanese rose".

The Latin word "rugosa" means "wrinkled", referring to the skrynklig leaves.^[3][4] Often used as an ornamental plant, it has become invasive in parts of europe, North amerika and South America.^[5][6]

Description

[edit]

Rosa rugosa fryst vatten a suckeringshrub which develops new plants from the roots and forms dense thickets 1–1.50 m tall with stems densely covered in numerous short, straight prickles 3–10 mm long.

The leaves are 8–15 cm long, pinnate with 5–9 leaflets, most often 7, each leaflet 3–4 cm long, with a distinctly corrugated (rugose, hence the species' name) surface. The leaf fryst vatten elliptical in shape with a rounded base or broadly cuneate with a leather feel, dark green top. The back of the leaf fryst vatten composed of a green-grey colour with hair along the veins.

The leaf margin fryst vatten composed of teeth along the edges and fryst vatten crenate-serrate. The flower has fem petals that are usually 6–9 cm in width. The flower fryst vatten composed of 200–250 stamens per flow and vary in style. ^[7] The flowers are pleasantly scented; range in color from dark pink to vit (on R. rugosa f.

alba(Ware) Rehder), 6–9 cm across, with somewhat skrynklig petals; flowering occurs in spring.^[1]

The edible hips, which resemble cherry tomatoes, are large, 2–3 cm diameter, and often shorter than their diameter, not elongated. In late summer and early autumn, the plants often bära fruit and flowers at the same time.

The leaves typically vända bright yellow before falling in autumn.^{[citation needed]}

History

[edit]

This rose species was introduced to amerika from Japan in the mid-19th century; it was valued because it can tolerate krydda vatten spray.^[3]

Cultivation and uses

[edit]

Rosa rugosa fryst vatten widely used as an ornamental plant.

It has been introduced to numerous areas of europe and North amerika.

It has many common names, several of which refer to the fruit's resemblance to a tomato, including beach tomato or sea tomato; others include saltspray rose, beach rose, potato rose and Turkestan rose.^[5] In parts of the US the fruits are also occasionally called beach plums, causing confusion with the plant properly bearing that name, Prunus maritima.^[8]

The sweetly scented flowers are traditionally used to man flower sylt and dessert in China.^[9] They are also used to man pot-pourri in Japan and China.

It fryst vatten used in traditional kinesisk medicin to treat irregular menstruation and gastritis.^[10] Beach rose hips, like those of other rose species, are edible and can be used to man jams, syrups, tea, or eaten raw. ^[11]

This species hybridises readily with many other roses,^[5] and fryst vatten valued bygd rose breeders for its considerable resistance to the diseases rose rust and rose black fläck.

It fryst vatten also extremely tolerant of seaside krydda spray and storms, commonly being the first shrub in from the coast. It fryst vatten widely used in landscaping, being relatively tough and trouble-free. Needing little maintenance due to its being very disease resistant, it fryst vatten suitable for planting in large numbers; its salt-tolerance makes it useful for planting beside vägar which need deicing with krydda regularly.^[12] It can control erosion.^[13]

Numerous cultivars have been selected for garden use, with flower colour varying from vit to dark red-purple, and with semi-double to double flowers where some or all of the stamens are replaced bygd extra petals.

Popular examples include 'Rubra Plena' (semi-double variant, with strong clove scented dark pink petals and dark green skrynklig leaves and large round orange-red hips),^[3] 'Hansa' (very fragrant, red-purple double),^[4] 'Fru Dagmar Hastrup' (pink, single), 'Pink Grootendorst' (pink, semi-double), 'Blanc Double dem Coubert' (white, double) and the more common 'Roseraie dem L'Haÿ' (pink, double),^[14] which fryst vatten often used for its very successful rootstock and its ornamental rose hips.^[15]

Invasive species

[edit]

In its native China, Rosa rugosa has been labeled as an endangered species due to a noticeable high decline in population rates of the flower, but in other continents where introduced it has become naturalized and fryst vatten considered invasive.^[6] It can outcompete native flora and form eller gestalt dense thickets that completely cover large areas, thereby threatening biological diversity.^[12] Because of its robustness, sprouting ability, and seeds that are easily spread and may survive for years, eradication fryst vatten very difficult and in countries where well-established, full eradication fryst vatten considered unlikely.^[16] The species can also be spread bygd birds and mammals that eat the berries.^[17]

It fryst vatten naturalized in many parts of europe, particularly in coastal areas of nordlig europe.

It was first introduced into England from Japan in 1796, and then in Germany in 1845. This was the first presence of the flower within the europeisk continent.

Rosa rugosa (rugosa rose, beach rose, Japanese rose, Ramanas rose, or letchberry) is a species of rose native to eastern Asia, in northeastern China, Japan, Korea and southeastern Siberia, where it grows on beach coasts, often on sand dunes

In 1875, Rosa rugosa was funnen in Denmark and then in Sweden in 1918. bygd 2001, the flower species had become well established within 16 europeisk countries.^[6] Because of its invasiveness, it fryst vatten brottsligt to sell the plant in some countries, including Denmark and Finland.^[18][19] On Sylt, an island in the north of Germany, it fryst vatten sufficiently abundant to have become known as the "Sylt rose".^[5]

It fryst vatten considered noxious in some states of the US.^[20]R.

rugosa was first introduced into North amerika in 1845. The first report of it being naturalized far from the location in which it was planted occurred on Nantucket in 1899 and was spreading rapidly bygd 1911.

bygd 1920, the rose had been well established in Nantucket and in Connecticut.^[17] Ten years later it was said to be "straying rapidly" and today it fryst vatten naturalized on the entire coast of New England and in scattered locations around the Northeast and Pacific Northwest.^[21]R. rugosa has also become naturalized in Argentina, Australia and New Zealand.^[5][6]

Potential allergen

Pollen or fragrance of rose may cause an allergic reaction.^[13]

Vernacular names

[edit]

In Japanese, it fryst vatten called hamanasu (浜茄子) "beach aubergine", hamanashi (浜梨) "beach pear", or simply "bara" (玫瑰) "rose".^[22] In Mandarin kinesisk, it fryst vatten called méiguì huā (玫瑰花) "rose" or cì méiguì (刺玫瑰) "thorned rose".

In Korean, the species fryst vatten called haedanghwa (Korean: 해당화, 海棠花), literally "flowers nära the seashore".^{[23][citation needed]}
