Abstract Sorghum halepense (L.) Pers. (Johnson grass, Poaceae) is a worldwide problematic alien species, rapidly expanding its alien range in Europe. This study reconstructed the spread history, and assessed the current distribution, ecological traits, and invasion potential of this species in the Insubric region of northern Italy and southern Switzerland. Herbarium and occurrence data showed that its spread began in the late 19th century and has accelerated recently in the foothill zone, progressing northward and upward. High-cover populations occurred in anthropogenic habitats, especially ruderal and agricultural areas. Morphological analyses revealed statistically significant site-dependent differences in plant height… More >
