Pamela Hopson, 26, jogs beneath jacaranda trees along Del Mar Boulevard in Pasadena. "I love hem. This is my favorite time of year," she says. "It's beautiful, and it is a mess. It's once a year we can deal with the mess." The trees infamously shed their flowers, frustrating property owners and gardeners. When smashed, the liquid inside the pods emits a sticky substance aphid waste in the bloom, not sap which can cause slippery pavement. Bug remover can usually remove the stickiness.
