The Invasive Pest Spotlight focuses on relevant or emerging invasive species in California. In this issue we are covering brooms, a group of invasive shrubs.
Invasive Broom facts
Brooms are upright shrubs in the legume family that typically produce small, yellow, pea-shaped flowers. Shrubs range from 3 to 10 feet tall. They produce flowers from mid spring to summer and produce seed pods in late summer.

You may see leafhoppers in your garden or landscape this time of year as they hop about feeding on a variety of plants. You can distinguish these small, wedge-shaped insects from other pests by their tendency to quickly jump or crawl rapidly sideways when disturbed.
Leafhoppers are sucking insects that insert their mouthparts into plants and suck out plant juices and cell contents. Damage occurs during feeding, which typically results in leaves looking stippled (little white dots), bleached, pale, or brown, and plant shoots may curl and die. You may notice a sticky residue on the plants called honeydew, a waste product from when some species of leafhoppers feed. A fungus called sooty mold may grow on the honeydew, which can be...
This week, we put the spotlight on invasive species and how these non-native plants, animals, and pathogens damage California's economy and environment.
