![]() The absolute is viscous oil of a dark-brown color. The absolute can be further treated to obtain a decolonized absolute.Ībout 1,200 kg of flowers are required to yield 1 kg of concrete which gives 0.30 to 0.35 kg of alcohol-soluble absolute. A more modern method is the extraction with volatile solvents, resulting in broom concrete, and on treatment with alcohol, in broom absolute. Alcohol extraction produced infusions or extracts, which were numbered according to the concentration of the flower oil they contained. In the past, enfleurage (cold fat) was the method used for obtaining the flower oil. Natural broom flower oil is produced in the Grasse region of Southern France and Italy. According to Guenther, the yellow-golden flowers possess an odor “reminiscent of orange blossoms and grape.” Another source describes the gen êt flower odor as “dusty-sweet, somewhat leathery and neroli-like.” Mode of Production, Type of Oil, Yield ![]() It grows wild in the Mediterranean countries. Of several species of Spartium (fam, Ieguminosae), known as broom, Spartium junceum L. There are several shrubs of the genus Genista (hence, the French name “Genêt” and “Ginster” in German). She is now the sole proprietor of From the Garden, a market garden farmette.English name "Broom" is literally derived from a broom being made from the plant’s twigs. Some information from King County, Washington California Invasive Plant Council, Berkeley, California.ĮLLEN PEFFLEY taught horticulture at the college level for 28 years, 25 of those at Texas Tech, during which time she developed two onion varieties. Cytisus scoparius is common broom or Scotch broom. Spanish Broom has naturalized in California, is considered invasive and is classified as a noxious weed in California and Washington State. The common sweet broom is Cytisus racemosus syn Genista racemosa. Because Spanish Broom is well adapted to sandy, rocky, low nutrient soil, it is widely used in xeriscapes. Spanish Broom was introduced into California as a garden ornamental in the 1850s and was planted along mountain highways and roadsides in Southern California in the1930s. Spanish Broom is native to the Mediterranean areas of Northern Africa, Western Asia and Southern Europe. Rejuvenation pruning also keeps the desired shape and size of the Spanish Broom. Younger branches are more floriferous than older stems, increasing flower production. The thinning out of older wood encourages new growth to be produced from the base. A rejuvenation cut is made by removing old, large stems near or at ground level, while leaving smaller, newer branches. ![]() To avoid "brooming," prune by making rejuvenation cuts. Over time, such spindly growth becomes unattractive and flowers will be produced only on the outer portions of the shrub. The broom-like regrowth is thin and spindly at the point where it was cut. Such clipping results in "broom-like" subsequent regrowth, in that clusters of new branches are produced at the tip of stems near the pruning point. Shrubs are frequently pruned by shearing or partially cutting back stems. There is a strategy to keep a Spanish Broom attractive. When Spanish Broom is left unchecked, it may outgrow its placement in the landscape. Scotch Broom flowers are similar but lack fragrance its stems are squared, bearing small, trifoliate leaflets. Spanish Broom has clusters of fragrant bright yellow flowers borne in clusters at the ends of rounded, bright green stems stems are usually leafless but it does sparsely produce single lance-shaped leaves that are less than 1 inch in length. Spanish Broom is often confused with Scotch Broom, but they are is easily distinguished. The Latin specific epithet junceum means "rush-like," referring to the shoots. The specific epitaph of Spanish Broom is Spartium junceum, while Scotch broom is Cytisus scoparius. While they are both members of the Fabaceae (pea) family and appear from a distance to be similar, upon closer inspection, they are quite different. ![]() To some folks these plants are almost interchangeable, but they are hardly the same. If you are anywhere near the golden-yellow flowering shrub with bright green foliage that is now in bloom everywhere around Lubbock, you will be cocooned within a heavy, sweet, pungent fragrance of the ornamental Spanish (or Weaver's) Broom - or is it the Scotch (Scot's or Scottish) Broom?
