[14] Invasive Himalayan balsam can also adversely affect indigenous species by attracting pollinators (e.g. Himalayan Balsam is the tallest annual plant in the UK growing up to 3 metres in height a year. ", "The biology of invasive alien plants in Canada. Its aggressive seed dispersal, coupled with high nectar production which attracts pollinators, often allow it to outcompete native plants. Commonly found along riverbanks and streams, around ponds and lakes, in wet woodlands and in ditches and damp meadows. The genus name Impatiens, meaning "impatient", refers to its method of seed dispersal. Cutting, strimming or pulling on a regular basis for about three years will be effective and may even eradicate the plant from isolated sites.

Up 15cm long. Grow up to 3m high. Himalayan balsam is an annual plant and grows very large for an annual species: up to two metres high or even more. How to get rid of Himalayan Balsam. Himalayan Balsam colonises areas rapidly and quickly outcompetes the surrounding vegetation and reduces diversity. [7], In Europe the plant was first introduced in the United Kingdom where it has become naturalized and widespread across riverbanks. Find the perfect himalayan balsam plant stock photo. Leaves are arranged opposite each other along stems. 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. Uprooting or cutting the plants is an effective means of control. (However, when number of flowers per floral unit, flower abundance, and phenology were taken into account it dropped out of the top 10 for most nectar per unit cover per year, as did all plants that placed in the top ten along with this one for per day nectar production per flower, with the exception of Common Comfrey, Symphytum officinale. [17] However, a study by Hejda & Pyšek (2006) concluded that, in some circumstances, such efforts may cause more harm than good. This method can also be used in conditions which would prevent foliar application of a herbicide. The young leaves have a neutral taste, the older leaves can be a bit bitter. During flood events the river banks are then vulnerable to floodwater because of the lack of perennial plants. A native of the Western Himalaya, it was introduced in 1839 and is now recorded throughout Britain. 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. [16], In the UK, the plant was first introduced in 1839, at the same time as giant hogweed and Japanese knotweed. Spraying needs to occur before the plant starts to flower but after the seed leaves have disappeared – from April to June to ensure that all the plants available for germination can be controlled. The elliptical leaves and side branches arise in whorls of 3-5 from stem joints. Glyphosate is the active ingredient in Roundup Pro Biactive, it 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. Himalayan Balsam is the tallest annual plant in the UK growing up to 3 metres in height a year. The shallow roots allow the plant to be pulled up right up to June when it flowers. Unlike Japanese Knotweed, Himalayan Balsam propagates via seeds, which will explode upon touch when ready. Himalayan balsam also promotes river bank erosion due to the plant dying back over winter, leaving the bank unprotected from flooding. Colonising rail and river banks, wastelands and woodlands, Himalayan balsam was introduced to the British Isles in 1839 by Victorian plant hunters who were keen on its beautiful pink flowers and exploding seed pods. The first indications that this would be a potentially invasive plant were the county Floras showing Himalayan Balsam tracing the line of waterways through the counties. The seeds of Himalayan Balsam are viable for up to two years and are commonly transported in waterways. It typically grows to 1 to 2 m (3.3 to 6.6 ft) high, with a soft green or red-tinged stem, and lanceolate leaves 5 to 23 cm (2.0 to 9.1 in) long. The researchers caution that their conclusions probably do not hold true for stands of the plant at forest edges and meadow habitats, where manual destruction is still the best approach. 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. Himalayan Balsam tends to grow near water and therefore the selection of an appropriate herbicide is limited. Glyphosate is the active ingredient in Asteroid Biocare, a full strength glyphosate packaged in 1 litre bottle with integrated measuring cap, allowing the product to be sold to the non professional user. The capsules open explosively when touched spreading the seeds up to 7 metres enabling the … The species name glandulifera comes from the Latin words glándula meaning 'small gland', and ferre meaning 'to bear', referring to the plant's glands. Stems are hollow. What is Himalayan balsam? Himalayan Balsam was added to schedule 9 of the Wildlife and Countryside Act 1981 in Wales and England. The green seed pods, seeds, young leaves and shoots are all edible. It has highly visible pink flowers on fleshy hollow stems that are green in the spring but become red as the year progresses. Grazing by cattle and sheep is effective from April throughout the growing season. This country later included it towards the end of 2011. As an annual it has a very shallow root system, barely adequate for its tremendous height. A distinctive characteristic of the plant are the seed capsules which provide its alternative name "Touch-me-not" Balsam. The crushed foliage has a strong musty smell. Within ten years, however, Himalayan balsam had escaped from the confines of cultivation and begun to spread along the river systems of England.[17]. Impatiens glandulifera is a large annual plant native to the Himalayas. The plant has had plenty of time to establish in the UK and, over the last 50 years, has spread rapidly. It is, however, a good nectar plant for bees and wasps in late summer. Plants are very invasive and can cover large areas – particularly close to watercourses. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. It is fast-growing and spreads quickly, invading wet habitat at the expense of other, native flowers. The flowers can be turned into a jam or parfait. The flowers are pink, with a hooded shape, 3 to 4 cm (​1.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px;white-space:nowrap} 1⁄4 to ​1 1⁄2 in) tall and 2 cm (​3⁄4 in) broad; the flower shape has been compared to a policeman's helmet. It is now widely established in other parts of the world (such as the British Isles and North America), in some cases becoming a weed. Because of the colour and type of the stem it has occasionally been mistaken by the uninitiated for Japanese knotweed. Impatiens glandulifera Royle", "Himalayan balsam, Impatiens glandulifera Geraniales: Balsaminaceae", "The potential influence of the invasive plant, Impatiens glandulifera (Himalayan Balsam), on the ecohydromorphic functioning of inland river systems", "The influence of an invasive plant species on the pollination success and reproductive output of three riparian plant species", "Identification Guide for Alberta Invasive Plants", "CABI releases rust fungus to control invasive weed, Himalayan balsam", Centre for Ecology and Hydrology: Centre for Aquatic Plant Management, Identifying and removing Himalayan Balsam, The UK Environment Agency's guide to managing invasive non-native plants, https://en.wikipedia.org/w/index.php?title=Impatiens_glandulifera&oldid=993155731, Creative Commons Attribution-ShareAlike License, This page was last edited on 9 December 2020, at 02:13. The elliptical leaves and side branches arise in whorls of 3-5 from stem joints. For the uniform cover, see. Leaves are stalked, oblong to egg-shaped and have a serrated edge. The green seed pods, seeds, young leaves and shoots are all edible and are traditionally used in curries in its native Himalayan region. Annual plants do not have the need for extensive root systems. Himalayan Balsam. Himalayan Balsam grows very rapidly which necessitates readily available access to soil moisture which is why it has colonised river banks which have an abundance of moisture and nutrients. [19], Some research also suggests that I. glandulifera may exhibit allelopathy, which means that it excretes toxins that negatively affect neighboring plants, thus increasing its competitive advantage. Differences. The Himalayan Balsam is a very adaptable survivor, to the rear of my border in amongst the Atlantic Delpiniums, (which I've removed the flower stems from as they are over and done with,) there are maybe a hundred HB's, but they are only max 18 inches tall and single stemmed, yet over in the wet ground with the montbretia (now there's a plant you cant get rid of) and the various flavours of mints and aqualigia … The capsules open explosively when touched spreading the seeds up to 7 metres enabling the plant to colonies new areas. The aeciospores enter the leaf through the stomata in a film of water, produced by dew or rain, and develop within the leaf feeding on the internal cells. A distinctive characteristic of the plant are the seed capsules which provide its alternative name "Touch-me-not" Balsam. Guidance notes for the use of herbicides in or near water. Himalayan balsam and kiss-me-on-the-mountain arise from the plant originating in the Himalayan mountains. Himalayan Balsam is a member of the Balsaminaceae family; also known as Touch-me-not Balsam and Policeman"s Helmet because of the shape of the flowers. Himalayan Balsam is tolerant of shade and it is now impossible to map the location of rivers using distribution maps of Himalayan Balsam because it has moved into woodland habitats and moist soils too. Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, and edible nectar. [17][18] These plants were all promoted at the time as having the virtues of "herculean proportions" and "splendid invasiveness" which meant that ordinary people could buy them for the cost of a packet of seeds to rival the expensive orchids grown in the greenhouses of the rich. 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. Plants have a thick, much branched, purple to reddish tinged stems. Guidance notes for the use of herbicides in or near water have been published by the Environment Agency.
