Brooms are a group of evergreen, semi-evergreen , and deciduous shrubs in the subfamily Faboideae of the pea family Fabaceae, mainly in the two genera Cytisus and Genista, but also in five other small genera (see box, right). All genera in this group are from the tribe Cytiseae . These genera are all closely related and share similar characters of dense, slender green stems and very small leaves, adaptations to dry growing conditions. Most of the species have yellow flowers, but a few have white, orange, red, pink or purple flowers. Two other close relatives are Ulex (Gorse) and Laburnum (Laburnum), but these differ more strongly in appearance from the brooms. Some botanists include Podocytisus caramanica in the genus Laburnum.
All the brooms and their relatives (including Laburnum and Ulex) are natives of Europe, north Africa and southwest Asia, with the greatest diversity in the Mediterranean region. Many brooms (though not all) are fire-climax species, adapted to regular stand-replacing fires which kill the above-ground parts of the plants, but create conditions for regrowth from the roots and also for germination of stored seeds in the soil.
The most widely familiar is the Common BroomCommon Broom Scientific classification Kingdom: Plantae Division: Magnoliophyta Class: Magnoliopsida Order: Fabales Family: Fabaceae Genus: Cytisus Species scoparius Binomial nomenclature Cytisus scoparius Common Broom Cytisus scoparius or Sarothamnus sco (Cytisus scoparius, a.k.a. Sarothamnus scoparius), a native of northwestern Europe, where it is found in sunny sites, usually on dry, sandy soils. Like most brooms, it has apparently leafless stems that in spring and summer are covered in profuse golden-yellow flowers. In late summer, its pea-pod like seed capsules burst open, often with an audible pop, spreading seed from the parent plant. It makes a shrub about 1-3m tall, rarely to 4m. It is also the hardiest broom, tolerating temperatures down to about -25°C.
The largest species of broom is the Mount Etna Broom (Genista aetnensis), which can make a small tree to 10m tall; by contrast, some other species, e.g. Dyer's Broom Genista tinctoria, are low sub-shrubs, barely woody at all.
Brooms tolerate and often thrive best in poor growing areas and conditions and need little care; they do though need good drainage and are poor on wet soils.
They have been widely used as ornamental landscape plants and also for wasteland reclamationLand reclamation is either of two distinct practices. Both involve modifying a land area into a desired state. However, one often involves restoring the land to a more natural state while the other is by definition a major change from the area's natural s (e.g. mine tailings) and sand dune stabilising. Species of broom popular in horticultureThe Latin words hortus ( garden plant) and cultura (culture) together form horticulture classically defined as the culture or growing of garden plants. Horticulture is, however, much more. Horticulturists work in plant propagation, crop production, plant are the Purple Broom (Chamaecytisus purpureus; purple flowers), Atlas Broom (Cytisus battandieri, a.k.a. Argyrocytisus battandieri), Dwarf Broom (Cytisus procumbens), Provence Broom (C. purgans) and Spanish Broom (Spartium junceum). Many of the most popular brooms in gardens are hybrids, notably Kew Broom (Cytisus x kewensis, hybrid between C. ardoinii and C. multiflorus) and Warminster Broom (Cytisus x praecox, hybrid between C. purgans and C. multiflorus).
The Dyer's Broom Genista tinctoria provides a useful yellow dyeA dye can generally be described as a coloured substance that has an affinity to the substrate to which it is being applied. The dye is usually used as an aqueous solution and may require a mordant to improve the fastness of the dye on the fibre. In contr.
In some areas of North AmericaNorth America is the third largest continent in area and the fourth ranked in population. It is bounded on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the south by the Caribbean Sea, and on the west by the North Pacific Ocea, the Common Broom, introduced as an ornamental plant, has become naturalised and an invasivePatterson's Curse infest the Warrumbungle National Park in New South Wales''. A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i. is not native), become weed due to its aggressive seed dispersal; it has proved very difficult to eradicate. Similarly, it is a major problem species in the cooler and wetter areas of southern Australia and New Zealand.
The Plantagenet kings originally used the broom ("planta genista") as an emblem, and took their name from it.
