Introduction to Impatiens glandulifera

Introduction to Impatiens glandulifera

Impatiens glandulifera - Roadside, Surrey

Impatiens glandulifera, commonly known as Himalayan Balsam, is a non-native invasive plant that is found in lowland, riparian areas, including moist forests, swamps, stream sides, ditches, and roadside. It is the largest annual plant in Britain, growing up to 2.5 meters tall with thick, hollow, translucent, and succulent stems. The plant has a shallow root system and can quickly colonize disturbed areas, outcompeting native vegetation and reducing biodiversity.

The plant was introduced from the Himalayas for ornamental purposes in 1839 and has since spread across much of the Northern Hemisphere. In Surrey, it is commonly found along roadsides, where it can form dense stands and displace native vegetation. The plant is partially shade tolerant and can grow in a wide range of soil types, making it highly adaptable to different environments.

Impatiens glandulifera is known for its explosive seed pods, which can shoot seeds up to seven meters away. The plant produces a large number of seeds, which can remain viable in the soil for up to five years, making it difficult to control. The plant is also known to reduce the levels of arbuscular mycorrhizal (AM) fungi in the soil, which can have negative impacts on native plant performance.

The City of Surrey has identified Impatiens glandulifera as an invasive species and has implemented measures to control its spread. These measures include manual removal, herbicide application, and the promotion of native vegetation to outcompete the plant. It is important to prevent the spread of this plant by not planting it in gardens and by properly disposing of any plant material.

If you spot Impatiens glandulifera along a roadside in Surrey, please report it to the City of Surrey's Invasive Species Program to help control its spread and protect our native ecosystems.

Habitat and Distribution of Impatiens glandulifera in Surrey

Impatiens glandulifera - Roadside, Surrey

Impatiens glandulifera, commonly known as Himalayan balsam, is a non-native invasive plant species that is found in Surrey and other parts of the UK. It is a large annual plant that can grow up to 2.5 meters tall and is native to the Himalayas. It was introduced to the UK in the 19th century as an ornamental plant, but it has since spread rapidly and is now considered a major problem in many areas.

The plant is found in lowland, riparian areas, including moist forests, swamps, stream sides, ditches, and roadside. It is partially shade tolerant and can grow in a wide range of soil types. It is known for its rapid growth and ability to outcompete native plant species, which can lead to a loss of biodiversity in affected areas.

One of the reasons why Himalayan balsam is such a successful invader is its ability to produce large quantities of seeds. The plant produces explosive seed pods that can shoot seeds up to 7 meters away from the parent plant. This allows the plant to quickly colonize new areas and outcompete native species.

Efforts are being made to control the spread of Himalayan balsam in Surrey and other parts of the UK. This includes manual removal of the plant, as well as the use of herbicides and biological control methods. However, controlling the spread of this invasive species is a challenging task, and it will require ongoing efforts to prevent further spread and protect native plant species.

If you come across Himalayan balsam in Surrey or other areas, it is important to report it to the local authorities and avoid spreading the seeds further. With proper management and control, it is possible to limit the impact of this invasive species and protect the natural environment.

Identification of Impatiens glandulifera

Impatiens glandulifera - Roadside, Surrey

Impatiens glandulifera, commonly known as Himalayan balsam, is a non-native invasive plant species that is found in Surrey and other parts of the UK. It is a large annual plant that can grow up to 2.5 meters tall and is native to the Himalayas. The plant was introduced to the UK in the 19th century as an ornamental plant, but it has since spread rapidly and is now considered a major threat to native plant species.

The plant is found in lowland, riparian areas, including moist forests, swamps, stream sides, ditches, and roadside. It is partially shade tolerant and can grow in a wide range of soil types. The plant has a hollow stem that is thick and translucent, and the leaves are green and serrated. The flowers are pink or purple and have a distinctive shape that resembles a helmet.

Impatiens glandulifera is a prolific seed producer, with each plant capable of producing up to 800 seeds. The seeds are dispersed by explosive seed pods that can shoot the seeds up to 7 meters away from the parent plant. This makes the plant highly invasive and difficult to control.

The plant has a negative impact on native plant species by outcompeting them for resources such as light, water, and nutrients. It also has a negative impact on the soil by reducing the levels of arbuscular mycorrhizal (AM) fungi, which are important for plant growth and nutrient uptake.

Efforts are being made to control the spread of Impatiens glandulifera in Surrey and other parts of the UK. This includes the use of biological control methods, such as the introduction of natural enemies of the plant, and manual removal of the plant from affected areas.

If you come across Impatiens glandulifera in Surrey or other parts of the UK, it is important to report it to the relevant authorities and not to attempt to remove it yourself. This will help to prevent the further spread of this invasive plant species and protect native plant species and ecosystems.

Ecological Impact of Impatiens glandulifera on Native Plants

Impatiens glandulifera - Roadside, Surrey

Impatiens glandulifera, commonly known as Himalayan balsam, is a non-native invasive plant species that has become a major problem in many parts of the world, including Surrey. It is a large annual plant that can grow up to 2.5 meters tall and is native to the Himalayas. It was introduced to the UK in the 19th century as an ornamental plant and has since spread rapidly, particularly along riverbanks and roadsides.

The plant has hollow stems and large, pink-purple flowers that bloom from June to October. It is a prolific seed producer, with each plant capable of producing up to 800 seeds that can be dispersed up to 7 meters away. The seeds can remain viable for up to two years, making it difficult to control the spread of the plant.

Impatiens glandulifera is a shade-tolerant plant that prefers moist soils and riparian areas, including stream sides, ditches, and roadside verges. It can outcompete native plant species, reducing biodiversity and altering the structure and function of ecosystems.

The plant is considered a major threat to native plant communities and has been listed as one of the top 20 invasive plant species in the UK. Efforts are being made to control its spread, including manual removal, herbicide application, and biological control using insects that feed on the plant.

If you come across Impatiens glandulifera in Surrey, it is important to report it to the local authorities and avoid spreading its seeds. Do not attempt to remove the plant yourself, as this can cause the seeds to spread further.

Control and Management of Impatiens glandulifera

Impatiens glandulifera, commonly known as Himalayan balsam, is a non-native invasive plant species that is found in lowland, riparian areas, including moist forests, swamps, stream sides, ditches, and roadside in Surrey, UK. It is the largest annual plant in Britain, growing up to 2.5 meters tall with thick, hollow, translucent, and succulent stems.

The plant was introduced to the UK in 1839 as an ornamental plant but has since become a problematic invasive species, outcompeting native plants and reducing biodiversity. It is also known by the common names policeman's helmet, ornamental jewelweed, and Indian balsam.

The plant is partially shade-tolerant and can grow in a wide range of soil types. It produces pink or purple flowers from June to October, which are attractive to pollinators such as bees and butterflies. The flowers are followed by explosive seed pods that can shoot seeds up to 7 meters away, aiding in its spread.

Efforts have been made to control the spread of Himalayan balsam in Surrey, including manual removal and herbicide application. Biological control methods, such as the introduction of a natural enemy, have also been explored.

If you come across Himalayan balsam in Surrey, it is recommended to report it to the local authorities and not to attempt to remove it yourself, as this can cause the plant to spread further.
