Lilac Tasselflower

The lilac tasselflower (Emilia sonchifolia) is an annual herb that is not native to California. It is believed to be from China or South-East Asia. The lilac tasselflower has high seed production, and spreads widely due to wind dispersal. Though not considered invasive in California, it's often reported as a weed for a number of crops. The lilac tasselflower weed is a vector for crop pathogens, and as a result can reduce crop yield. It grows in many different environments, from the tropics to grasslands. Another common name for the lilac tasselflower is Cupid's shaving brush. Can you see why?
