Spanish broom occurs in other states as a cultivated ornamental Spanish broom's North American distribution is from Washington to southern California Including Spain, Morocco, the Canary Islands, Madeira, and the Azores. Spanish broom is native to the southern Mediterranean region of Europe, Hazard during the dry season, because patches can be dense and may contain a While this is particularly true for gorse and French broom, Nilsen Īlso suggests that mature Spanish broom stands should be considered a fire Īccording to a review by DiTomaso, dense broom infestations produce substantial dry matter that can create a seriousįire hazard. Environmental varianceĪccounts for a large proportion of the variance in physiological traits, andĪbout 33% of the variance in growth traits. Variance was similar between the 2 population types. In contrast,įew mean physiological traits differed between ramet and genet populations, and In leaves, and more roots compared with cloned individuals. Whole plant dry mass per shoot length, a higher percentage of total biomass Tended to be higher in genet populations. (P<0.05) different between ramet and genet populations, and the variance in these traits In a greenhouse study, several mean growth traits were significantly īotanical traits of Spanish broom vary somewhat between cloned individualsĪnd those grown from seed. The constant carbon gain throughout the year, from stem assimilation, may enhance the growthĬapacity of both species in disturbed habitats. Intercellular carbon dioxide is lower for Spanish broom compared to Scotchīroom. Vapor pressure is similar between species. Habitats with different vapor pressure and temperature, assimilation response to Per day carbon dioxide assimilation on study sites in California. Positive stem assimilation resulting in approximately 200 mmol per m² Have a constant positive carbon balance due to stem photosynthesis. Strain by changing the organization of its root system, particularly in the up-slopeĪlthough the leaves of both Spanish broom and Scotch broom are ephemeral, their canopies This suggests that Spanish broom reinforces its anchorage System was modified on a slope by an increase in the length and number of rootĪpices of 1st-, 2nd-, and 3rd-order lateral roots. The authors observed that the overall architecture of the root Growing in 3 different rooting environments in Italy: terrace, plane, and 40° Structure or morphology are available for plants growing in North America.Ĭhiatante and others describe root morphology of Spanish broom Fruit is a linear, dehiscent legume, 2 to 4 inches (5-10 cm) longĪt the time of this writing (2005), no descriptions of Spanish broom root Large, pea-like, up to 1 inch long, and grow on short stalks on both sides of Terminal raceme with several flowers located on current-year shoots. Remaining on the plant for 4 months or less. Small, 0.5 to 1 inch (2-2.5 cm) long, oval, and smooth-margined. Stems areĬylindrical, rush-like, and green when young, maturing into woody branches with bark. Its long, slender stems are erect with few branches. Spanish broom is a tall shrub to small tree, up to 10 to 15 feet (3-5 m) A key for identification is available in Hickman. It providesĬharacteristics that may be relevant to fire ecology, and is not meant for Summary of the range of characteristics described in reviews and florae. The following description of Spanish broom provides a According to DiTomaso Spanish broom may haveĮcological characteristics similar to Scotch broom. Spanish broom is not as widely distributed norĪnd less is known about its biology and ecology. Is morphologically distinct from the brooms. Have some similar morphological characteristics, while common gorse Spanish broom, French broom, Scotch broom and Portuguese broom All are perennial, leguminous shrubs.ĭiTomaso provides a table of characteristics to distinguishĪmong broom species and common gorse. Spanish broom is 1 of 4 nonnative invasive broom species that occur in More info for the terms: dehiscent, fruit, genet, ramet, seed, shrub, shrubs, tree
