Plants are very invasive and can cover large areas – particularly close to watercourses. Himalayan balsam and kiss-me-on-the-mountain arise from the plant originating in the Himalayan mountains. (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. ", "The biology of invasive alien plants in Canada. The shallow roots allow the plant to be pulled up right up to June when it flowers. Due to its seasonal nature, Himalayan balsam can leave entire stretches of riverbanks bare during the winter, leaving the area more susceptible to land erosion. [2] Via human introduction it is now present across much of the Northern Hemisphere and is considered an invasive species in many areas. [11] In the United States it is found on both the east and west coast, seemingly restricted to northern latitudes. Himalayan Balsam. Guidance for the control of invasive weeds in or near fresh water. It produces seedpods which explode when ripe spreading the seeds up to … As an annual it has a very shallow root system, barely adequate for its tremendous height. Himalayan Balsam also causes a less obvious problem for native species. [14] Invasive Himalayan balsam can also adversely affect indigenous species by attracting pollinators (e.g. It is, however, a good nectar plant for bees and wasps in late summer. Impatiens glandulifera is a large annual plant native to the Himalayas. Guidance notes for the use of herbicides in or near water. There are several steps you can take to stop the spread of invasive plants, including: 1. know what is growing in your garden – you can get help identifying invasive plants on the Invasive Species Ireland website(external link opens in a new window / tab) 2. manage invasive species on your land – the Invasive Species Ireland website(external link opens in a new window / tab)provides advice for a wide range of species 3. dispose of all plant waste responsibly – it is illegal to plant or cause the spread of m… Himalayan Balsam is an annual plant; growing from seed, flowering and setting seed within a year before dying. Find the perfect himalayan balsam plant stock photo. Cutting the plants down to ground level can stall their progress, but by sure to plan your attack for the end of June; too late and you risk spreading the seeds, too early and you risk precipitating a regrowth of new stems. Plants have a thick, much branched, purple to reddish tinged stems. I found a reference to a distillery adding dried Himalayan Balsam flowers to one of its gins to create a limited pink edition, but they didn’t share their recipe, so I decided to create my own. Like many flowering plants, Himalayan Balsam produces a sugary nectar to attract insects. All Himalayan balsam plants germinate from the previous year"s seed. Uprooting or cutting the plants is an effective means of control. Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, and edible nectar. This leaves the … 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. A distinctive characteristic of the plant are the seed capsules which provide its alternative name "Touch-me-not" Balsam. If … Within ten years, however, Himalayan balsam had escaped from the confines of cultivation and begun to spread along the river systems of England.[17]. Roots are up to 15 cm deep, the plants often forming numerous adventitious roots from the lower nodes. The crushed foliage has a strong musty smell. )[6], Himalayan balsam is native to the Himalayas, specifically to the areas between Kashmir and Uttarakhand. Himalayan Balsam is the tallest annual plant in the UK growing up to 3 metres in height a year. Plants must be cut below the lowest node to avoid reflowering. Its aggressive seed dispersal, coupled with high nectar production which attracts pollinators, often allow it to outcompete native plants. What does Himalayan balsam look like? However the flowers produce more nectar than any other native European species making it more attractive to bees and other insects, luring them away from pollinating our native flowers. Stems are hollow. Characteristics of Himalayan Balsam Himalayan Balsam is a large plant, normally reaching 1 to 2 metres in height, although in some cases it can grow as tall as 2.5 metres. Himalayan balsam is an annual plant (it completes its lifecycle within one year), which grows to 2m tall with rough, reddish stems, shiny oval leaves about 15cm long with a red vein, and bright purple-pink flowers from June-September. If all goes well, the project will have it financing its own eradication. Webb, D.A., Parnell, J. and Doogue, D. 1996. The young leaves have a neutral taste, the older leaves can be a bit bitter. Grow on stem in whorls of three. Himalayan balsam has a very shallow root making uprooting by hand easy. The capsules open explosively when touched spreading the seeds up to 7 metres enabling the … 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. insects) at the expense of indigenous species. The species name glandulifera comes from the Latin words glándula meaning 'small gland', and ferre meaning 'to bear', referring to the plant's glands. Leaves are arranged opposite each other along stems. 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 research suggests that the best way to control the spread of riparian Himalayan balsam is to decrease eutrophication, thereby permitting the better-adapted local vegetation, that gets outgrown by the balsam on watercourses with high nutrient load, to rebound naturally. It has highly visible pink flowers on fleshy hollow stems that are green in the spring but become red as the year progresses. It should be continued until no new growth occurs. 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 pulling technique must be undertaken so that whole plant is uprooted and normally best done if pulled from low down the plant - If snapping occurs at a node the pulling must be completed to include the roots. This country later included it towards the end of 2011. Himalayan balsam (Impatiens glandulifera) has rapidly become one of the UK’s most invasive weed species, colonising river banks, waste ground and damp woodlands. In August 2014, CABI released a rust fungus in Berkshire, Cornwall and Middlesex in the United Kingdom as part of field trials into the biological control of Himalayan balsam. Himalayan Balsam tends to grow near water and therefore the selection of an appropriate herbicide is limited. The serrated leaves grow along the stem joints either in pairs or whorls of three. [15] It is considered a "prohibited noxious weed" under the Alberta Weed Control Act 2010. Himalayan balsam is an introduced annual naturalised along riverbanks and ditches. Cutting, strimming or pulling on a regular basis for about three years will be effective and may even eradicate the plant from isolated sites. Guidance notes for the use of herbicides in or near water have been published by the Environment Agency. The elliptical leaves and side branches arise in whorls of 3-5 from stem joints. 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 also edible and are used in jellies and wines. 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. Himalayan Balsam regrows annually from the seeds which are viable for 2 years therefore any control ... Leaves Green large narrow leaves with serrate edges. Himalayan Balsam is the tallest annual plant in the UK growing up to 3 metres in height a year. After flowering between June and October, the plant forms seed pods 2 to 3 cm (​3⁄4 to ​1 1⁄4 in) long and 8 mm broad (​1⁄4 in), which explode when disturbed,[4] scattering the seeds up to 7 metres (23 feet). Himalayan balsam also promotes river bank erosion due to the plant dying back over winter, leaving the bank unprotected from flooding. Himalayan balsam tolerates low light levels and also shades out other vegetation, so gradually impoverishing habitats by killing off other plants. The flowers can be turned into a jam or parfait. [21][22] Introduced to the UK in 1839, Himalayan balsam is now a naturalised plant, found especially on riverbanks and in waste places where it has become a problem weed. What is Himalayan balsam? In its native range it is usually found in altitudes between 2000–2500 m above sea level, although it has been reported in up to 4000 m above sea level. Himalayan Balsam (Impatiens glanulifera) is an attractive looking flower, with a stout, hollow stem, trumpet shaped pink/white flowers and elliptical shaped green leaves. 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. Unlike Japanese Knotweed, Himalayan Balsam propagates via seeds, which will explode upon touch when ready. Differences. The green leaves are long and pointed and typically around 5 to 8 cm in length. Stem Hollow, sappy, and brittle stems. "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?

A very invasive, non-native plant which is illegal to grow or cause the growth of. [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. Leaves are long, slender and shiny, with serrated edges and are dark green in colour. Plants have a poor root structure so it is relatively easy to remove. The common names policeman's helmet, bobby tops, copper tops, and gnome's hatstand all originate from the flowers being decidedly hat-shaped. Because of the colour and type of the stem it has occasionally been mistaken by the uninitiated for Japanese knotweed. [23], Himalayan balsam at Bank Hall, Bretherton, Lancashire, England, "Policeman's helmet" redirects here. The plant has had plenty of time to establish in the UK and, over the last 50 years, has spread rapidly. 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. It is illegal to move soil which contains its seeds and accidentally spreading them and its … The Injectordos Pro Stem Injection Kit will limit the herbicide to treating specific plants, creating minimum disturbance in the surrounding vegetation and enabling the surrounding vegetation to spread quickly back into affected areas. [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. Himalayan balsam; Rhododendron ponticum; New Zealand pigmyweed (this is banned from sale) You do not have to remove these plants or control them on your land. A native of the Western Himalaya, it was introduced in 1839 and is now recorded throughout Britain. The genus name Impatiens, meaning "impatient", refers to its method of seed dispersal. 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. [13], Himalayan balsam is sometimes cultivated for its flowers. It is fast-growing and spreads quickly, invading wet habitat at the expense of other, native flowers. 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. Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, and edible nectar. Natural Resources Wales has used manual methods, such as pulling plants and using strimmers, to largely eradicate Himalayan Balsam from reaches of the River Ystwyth. The seeds have a pleasant nutty taste and seem better when pale in colour before turning black and becoming quite hard. Himalayan Balsam colonises areas rapidly and quickly outcompetes the surrounding vegetation and reduces diversity. No need to register, buy now! 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. Grazing by cattle and sheep is effective from April throughout the growing season. It prefers moist soils but will grow anywhere. One Himalayan balsam plant is said to be able to spread 2,500 seeds alone; surveyors advise homeowners to remove this weed due to its ability to … Despite its large size its root system is fairly shallow, only to about fifteen centimetres deep. Himalayan balsam is easily identifiable with its whorled leaves (usually in threes). Himalayan balsam is an annual, however, and it dies back in the winter, leaving bare spaces that would normally be inhabited by native grasses. The inflorescences are racemes of 2-14 flowers that are 25-40 mm long. Himalayan Balsam was added to schedule 9 of the Wildlife and Countryside Act 1981 in Wales and England. 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 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. Himalayan Balsam has been added to Schedule 9 by The Wildlife and Countryside Act 1981 (Variation of Schedule 9) (England and Wales) Order 2010: this means that it is illegal to plant or otherwise cause to grow Himalayan Balsam in the wild. 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. Himalayan balsam will grow up to around 1-2m high and between roughly June and October, it will produce a cluster of purple/pink helmet-shaped flowers that has been compared to a policeman’s … Commonly found along riverbanks and streams, around ponds and lakes, in wet woodlands and in ditches and damp meadows. During flood events the river banks are then vulnerable to floodwater because of the lack of perennial plants. Annual plants do not have the need for extensive root systems. How to get rid of Himalayan Balsam. Even if you accidentally cause this plant to grow you could face criminal charges. [17] However, a study by Hejda & Pyšek (2006) concluded that, in some circumstances, such efforts may cause more harm than good. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. [7] Presently it can be found almost everywhere across the continent. [12], In New Zealand it is sometimes found growing wild along riverbanks and wetlands. The crushed foliage has a strong musty smell.

[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. There are also claims that the height of the plant causes a problem by restricting the flow of the river. 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. This method can also be used in conditions which would prevent foliar application of a herbicide. A distinctive characteristic of the plant are the seed capsules which provide its alternative name "Touch-me-not" Balsam. Himalayan balsam grows up to 3 m tall and is reputed to be the tallest annual plant found in the UK. [5], The plant was rated in first place for per day nectar production per flower in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. The crushed foliage has a strong musty smell. The Act makes it an offence to grow Himalayan Balsam in the wild. The seeds of Himalayan Balsam are viable for up to two years and are commonly transported in waterways. Green to red. It grows in dense stands and can be up to 2m tall. For the uniform cover, see. 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. The green seed pods, seeds, young leaves and shoots are all edible and are traditionally used in curries in its native Himalayan region. The green seed pods, seeds, young leaves and shoots are all edible. 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. Riparian habitat is suboptimal for I. glandulifera, and spring or autumn flooding destroys seeds and plants. 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. Leaves are stalked, oblong to egg-shaped and have a serrated edge. Leaves opposite, or in whorls of 3-5 Leaf may have reddish mid-rib Side shoots/ roots form along stem Leaves have finely serrated edges Slender to elliptical Short roots with distinctive structure Stem is hollow, sappy, fleshy and brittle Stem green to red early in the year, turning pink to red in summer Leaves and side branches arise from stem joints Seeds Grow up to 3m high. 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. 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 … Himalayan balsam is an annual plant and grows very large for an annual species: up to two metres high or even more. It successfully competes with native plant species for space, light, nutrients and pollinators, and excludes other plant growth, thereby reducing native biodiversity. The aeciospores are spread by wind and rain, and infect the leaves of Himalayan balsam. 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. © 2020 Agrovista UK Ltd - Pitchcare.com is a trading name of Agrovista UK Ltd, a company registered in England and Wales. Destroying riparian stands of Himalayan balsam can open up the habitat for more aggressive invasive plants such as Japanese knotweed and aid in seed dispersal by dropped seeds sticking to shoes. [16], In the UK, the plant was first introduced in 1839, at the same time as giant hogweed and Japanese knotweed.

Himalayan balsam is the tallest annual plant in the UK, growing up to 2.5m; thus reaching the same height as some mature knotweed. [7], In Europe the plant was first introduced in the United Kingdom where it has become naturalized and widespread across riverbanks. 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. 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 now spread across most of the UK, and some local wildlife trusts organise "balsam bashing" events to help control the plant. Himalayan balsam grows up to 3 metres high with a hollow and bamboo-like stem, pink-red to green in colour with green vertical grooves. It has an explosive seed capsule, which scatters seeds over a distance of up to 7m. The elliptical leaves and side branches arise in whorls of 3-5 from stem joints. It has highly visible pink flowers on fleshy hollow stems that are green in the spring but become red as the year progresses. 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. Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, nectar. Himalayan Balsam is not a native species to the UK originating, as the name implies, in the Himalayas. 9. [3] Ornamental jewelweed refers to its cultivation as an ornamental plant. The Bionic Control of Invasive Weeds project, in Wiesbaden, Germany, is trying to establish a self-sufficient means of conserving their local biodiversity by developing several food products made from the Himalayan balsam flowers. Up 15cm long. [20], The Royal Horticultural Society and the Centre for Ecology and Hydrology recommend that pulling and cutting is the main method of non-chemical control, and usually the most appropriate. 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.
