Campanula rhomboidalis

Campanula rhomboidalis L. (Alps, Jura) – A very rare, locally naturalised but much decreasing alien. Probably introduced in the second half of the 19th century (although not collected before 1966) with alpine grass seed in meadows around Lommel and Neerpelt (Mertens & Simons 1982), along with other curiosities like Cirsium rivulare. Contrary to Berten (2006) Campanula rhomboidalis lately much decreased and only survives in one (transplanted) location (comm. Arnout Zwaenepoel). In its single Belgian population it only survives as a result of conservation management. In the Netherlands Campanula rhomboidalis was formerly recorded in identical circumstances (Kloos 1950). Exceptionally seen elsewhere, for instance in a road verge in Wortegem in 1949.
