![]() Then follow with controlled burning to prevent the plant from re-sprouting. You can also cut the green foliage and let the stems dry out. Chop out the plant in spring when the soil is moist and has some give. This can be difficult on plants like Scotch broom, which may have a 6-foot (1.8 m.) long taproot. Their adaptability and rapid growth can lead to an invasive tendency in some areas.Ĭontrolling broom shrubs with mechanical pulling and cultural management can help in areas with low infestations. They establish quickly in disturbed areas, but also in grassland and forests. The only space that is not pleasing to broom shrubs is a soggy, boggy and shady location. Rather than ask, where do broom shrubs grow, you should ask, where don’t they grow. ![]() The bright yellow flowers have a pea-pod like appearance which yield to black or brown pods filled with dark green seeds in late summer. ![]() Spanish broom is so closely angled that it appears almost round. Scotch broom has a five-sided stem while French and Portuguese have 8 and 10 angled stems. Stem shape separates the broom shrub varieties. – 3 m.) tall with angled stems and small simple to trifoliate leaves. There are several broom shrub varieties but the most common are the Scotch and Spanish, which were introduced as erosion control.īrooms can get 3 to 10 feet (92 cm. The stems die back in dry weather and produce flammable “torches” of plant material. Brooms produce wide branching root systems and thick tenacious stems. This speedy development makes the plants a threat to native species. The plants have become quite invasive with seeds spreading and sprouting quickly. About Broom Shrub Plantsīrooms form small to large shrubs that grow very quickly. The plant can get a bit invasive in some areas though, but a little information on broom shrubs will help you control the plants while still enjoying their ease of care and brilliant blooms. Broom shrub plants may get 9 feet (2.5 m.) tall and produce some spectacular bloom displays in spring. Most broom shrub varieties were originally introduced as ornamentals but some species became useful as erosion control. Prepared by Kelly Reeves, Southern Colorado Plateau Network Inventory and Monitoring Program, 2010.Broom plants, such as Scotch broom ( Cytisus scoparius), are common sights along highways, in meadows and in disturbed areas. US Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory. ![]() Department of Agriculture, Forest Service, Washington, DC. Cytisus scoparius (L.)

California plant names: Latin and Greek meanings and derivations. 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. Fruit is a brownish-black pod with hairs only along the seams.Small leaves occur together in groups of three.Scotch broom is a shrub with bright yellow flowers and stiff, slender branches.
