Notes about the naturalization in Sicily of Paulownia tomentosa (Paulowniaceae) and remarks about its global spread

Abstract

Paulownia tomentosa is native to different regions of East Asia. Here, the first case of natural regeneration in Sicily is reported. Although Paulownia is not still invading typically Mediterranean areas, mainly due to ecological constraints, its recognized invasiveness at a global level imposes the need to monitor the ongoing process.
