Buddleja madagascariensis is considered a serious invader in Hawaii at 900–1200 m, where it sets abundant fruits (Hawaii Invasive Species Council, https://dlnr.hawaii.gov/hisc/info/species/smoke-bush/); this contrasts with the report by A. J. M. Leeuwenberg (1979) that he had observed specimens with fruits only from Crete, Madagascar, and Mauritius.
