Himalayan balsam was introduced as a garden plant in 1839, but soon escaped and became widely naturalised along riverbanks and ditches, especially close to towns. The leaves are opposite, the upper ones sometimes in whorls of three, up to 25 cm long and 7 cm wide, lanceolate to obovate, petiolate and sharply serrated at the edges. Grow up to 3m high. Himalayan balsam is an introduced annual naturalised along riverbanks and ditches. Because of the colour and type of the stem it has occasionally been mistaken by the uninitiated for Japanese knotweed. Cutting, strimming or pulling on a regular basis for about three years will be effective and may even eradicate the plant from isolated sites. [8][9][10], In North America it has been found in the Canadian provinces of British Columbia, Manitoba, Ontario, Quebec, Nova Scotia, New Brunswick, Prince Edward Island and Newfoundland. In terms of the negative pollinator effect with Himalayan balsam, there is evidence to suggest the opposite, that there is what they call an adjacent benefit, so that other native riparian riverside species that are flowering at the same time receive more visits rather than less when they’re kind of in the same area as Himalayan balsam, Himalayan being super popular with honeybees and … The capsules open explosively when touched spreading the seeds up to 7 metres enabling the plant to colonies new areas. 9. This causes a problem because Himalayan Balsam does not have an extensive root system and it is crowding out perennial plants that bind the river banks with their root systems. 2-4-D amine is the active ingredient in Depitox, a selective herbicide that controls broadleaved weeds and correctly applied will not damage grasses thereby preventing new Himalayan Balsam seeds from becoming established however 2-4-D amine is a professional herbicide and requires the user to have a pesticide application license. It has highly visible pink flowers on fleshy hollow stems that are green in the spring but become red as the year progresses. [14] Invasive Himalayan balsam can also adversely affect indigenous species by attracting pollinators (e.g. [3] Ornamental jewelweed refers to its cultivation as an ornamental plant. A weed wipe can be used for small infestations although in all likelihood a small area would be easier to control by physically removing it by pulling it up. Within ten years, however, Himalayan balsam had escaped from the confines of cultivation and begun to spread along the river systems of England.[17]. A distinctive characteristic of the plant are the seed capsules which provide its alternative name "Touch-me-not" Balsam. The green seed pods, seeds, young leaves and shoots are all edible. Grazing by cattle and sheep is effective from April throughout the growing season. It should be continued until no new growth occurs. The crushed foliage has a strong musty smell. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. A weed wipe can be used for small infestations although in all likelihood a small area would be easier to control by physically removing it by pulling it up. The flowers are pink, with a hooded shape, 3 to 4 cm (​1 ⁄4 to ​1 ⁄2 in) tall and 2 cm (​ ⁄4 in) broad; the flower shape has been compared to a policeman's helmet. It has an explosive seed capsule, which scatters seeds over a distance of up to 7m. Up 15cm long. If all goes well, the project will have it financing its own eradication. "The Plant List: A Working List of All Plant Species", "Gastronomie: Springkraut & Co.: Kräuterkoch Peter Becker macht aus Neophyten Salat", "Which flowers are the best source of nectar? Himalayan Balsam also causes a less obvious problem for native species. Commonly found along riverbanks and streams, around ponds and lakes, in wet woodlands and in ditches and damp meadows. Himalayan Balsam (Impatiens glanulifera) is an attractive looking flower, with a stout, hollow stem, trumpet shaped pink/white flowers and elliptical shaped green leaves. Impatiens glandulifera is a large annual plant native to the Himalayas. The elliptical leaves and side branches arise in whorls of 3-5 from stem joints. [16], In the UK, the plant was first introduced in 1839, at the same time as giant hogweed and Japanese knotweed. Himalayan Balsam is an annual plant; growing from seed, flowering and setting seed within a year before dying. The crushed foliage has a strong musty smell. Despite its large size its root system is fairly shallow, only to about fifteen centimetres deep. Asteroid Biocare is a very effective herbicide that starts to degrade almost as soon as it is applied however it is not selective and will kill any plant it comes into contact with. It is fast-growing and spreads quickly, invading wet habitat at the expense of other, native flowers.
