The name tasselflower refers to two similar and closely related species of genus Emilia, Emilia sonchifolia (red tasselflower or lilac tasselflower) and Emilia fosbergii (Florida tasselflower). Both species are very similar in appearance but can be distinguished by small differences in their leaves and flower structures. These species are very common in Florida nurseries, greenhouses, and landscapes. This study by the University of Florida was conducted to help nursery growers, landscape professionals, and the general public identify tasselflower species, understand their biology, and provide information on ways to manage this weed.
The study is conducted by Yuvraj Khamare, Chris Marble, Shawn Steed and Nathan Boyd.
