![]() ![]() Seed can remain viable in the soil for many years. Seeds of these species have a hard coat that can delay germination for months or years, allowing large seed banks to develop. The ability of the plants to shoot their seeds some metres away allows infestations to thicken quickly and to spread, particularly along water courses. Their pods burst open in hot weather during spring and summer, scattering seeds up to several metres from the plant. ![]() Their main method of spread is now via seed by soil, water, machinery, footwear, stock and wildlife. Originally, both gorse and brooms were planted as hedge or ornamental garden plants. Record the presence of priority weeds in their council area and provide this to the NSW Department of Primary Industries. These records are made by authorised officers during property inspections under the Biosecurity Act 2015. Recorded presence of Scotch broom during property inspections (Map: Biosecurity Information System - Weeds, 2017-2023).Some large populations of Scotch broom exist on the Barrington Tops and near Braidwood. Gorse is a problem in the south-eastern region of the state and the Blue Mountains. Gorse and brooms are mostly confined to cool temperate areas of NSW, particularly the tablelands. If going to a hospital take a piece of the plant for identification.If the patient is conscious and responsive call the Poisons Information Centre on 13 11 26 or your doctor.If the patient is unconscious, unresponsive or having difficulty breathing dial 000 or get to the emergency section of a hospital immediately. ![]() If ingested in large amounts the toxins contained in scotch broom can weaken the heart. The seeds and leaves are poisonous and can cause high blood pressure and nausea if ingested. Scotch broom is toxic to humans and will cause discomfort and irritation, but is not life-threatening. They form dense thickets which can block access by humans and stock but harbour feral animals such as rabbits, foxes and pigs. Scotch broom will smother desirable vegetation which reduces pasture stocking rates. This plant must not be sold anywhere in NSW Prepared by Kelly Reeves, Southern Colorado Plateau Network Inventory and Monitoring Program, 2010.This plant is a Weed of National Significance US Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory.

University of California Press, Berkeley, CA.Ĭharters, M. Invasive plants of California’s wildlands. In addition, Scotch broom is slightly toxic and unpalatable to livestock.īossard, C. Several characteristics contribute to its success as an invasive plant: (1) although it loses its leaves during dry conditions, the photosynthetic tissue in its stems allows it to grow throughout the year (2) its roots host nitrogen-fixing bacteria, which helps the plant to establish in nutrient-poor soils and (3) it produces abundant seeds that remain viable in the soil for many years. Scotch broom invades dry hillsides, pastures, forest clearings, dry scrublands, dry riverbeds, and waterways. ![]() However, it does not tend to survive in very arid or cold areas. Scotch broom flourishes in full sunlight in dry, sandy soils, but it can survive under a wide variety of soil conditions. Later, it was used for erosion control along highway cuts and fills. From the 1850s through the early 1900s, Scotch broom was frequently planted in gardens. Native to northern Africa and parts of Europe, it was first introduced to North America on the east coast and was later introduced to California as an ornamental. Scotch broom ( Cytisus scoparius) is found along the east and west coasts of North America and in Idaho, Montana, and Utah.
