![]() Ashes of broom were used to treat dropsy, while its strong smell was said to be able to tame wild horses and dogs. Most of the species have yellow flowers, but a few have white, orange, red, pink or purple flowers.Ī traditional rhyme from Sussex says: "Sweep the house with blossed broom in May/sweep the head of the household away." Despite this, it was also common to include a decorated bundle of broom at weddings. These genera are all closely related and share similar characteristics of dense, slender green stems and very small leaves, adaptations to dry growing conditions. ![]() All genera in this group are from the tribe Genisteae (syn. The brooms belong to the subfamily Faboideae of the legume family Fabaceae, mainly in the three genera Chamaecytisus, Cytisus and Genista, but also in five other small genera (see box, right). Scotch broom is a bushy, drought-deciduous shrub that grows three to six feet tall. It is also the hardiest broom, tolerating temperatures down to about -25 ☌. It makes a shrub about 1–3m tall, rarely to 4m. In late summer, its pea-pod like seed capsules burst open, often with an audible pop, spreading seed from the parent plant. Like most brooms, it has apparently leafless stems that in spring and summer are covered with golden-yellow flowers. ![]() One can find it in sunny sites, usually on dry, sandy soils. The most familiar is common broom, that grows in northwestern Europe. 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 greatest diversity one can find in the Mediterranean region. This is the northern part of SDC between the two bridges crossing over Sonoma Creek.Brooms are a group of evergreen, semi-evergreen, and deciduous shrubs.Īll the brooms and their relatives (including Laburnum and Ulex) grow in Europe, north Africa and southwest Asia. We will be meeting in the parking lot of the old farmhouse/superintendent house on the SDC campus, located along Arnold Drive across from the parking area for Sonoma Valley Regional Park. Where: Western side of Arnold Drive in Sonoma Developmental Center (see directions below) What: Broom pull, an outdoor volunteer event All ages are welcome (children must be accompanied by an adult). Please wear sturdy shoes and clothes you don’t mind getting dirty in. Gloves and tools as well as drinks and snacks will be provided. ![]() That means now, and Mills said he is excited to spend the two days outside with fellow Sonoma Valley residents, working together to slow the spread of this pernicious plant. “I’ve been involved with its control for nearly 20 years now and have developed a systematic approach that has been effective.” Two important rules, he said, are don’t mow it, and try to pull it up while the ground is still wet. French Broom is a serious problem in California and the West Coast because it dominates native plant environments and stops the natives from growing, the main food sources for animals, birds, and it's toxic. “Broom is a highly invasive species here on the Central Coast,” Mills said. These are family-friendly events where volunteers join us in a beautiful outdoor location – in Sonoma Developmental Center on sites where fire swept through in October 2017 – and help restore it to its natural glory. To slow its spread, Mills and the Restoration Department are inviting the public to take part in two outdoor “broom pull” events this month, on April 13 and April 22. But French broom is unwanted here because it’s environmentally destructive, a fire hazard, and very hard to control.Īnd according to Sonoma Ecology Center Restoration Program Manager Jason Mills, French broom ( Genista monspessulana) has been especially virulent this spring in Sonoma Valley’s post-fire areas. With the arrival of spring, the invasive shrub called French broom, with its long woody stalks and pretty yellow flowers, is popping up all over Sonoma Valley.
