Montbretia (various Crocosmia hybrids and varieties) was introduced as a garden plant in the late 19th century and had already become naturalised by the beginning of the 20th century. It is spread by rhizomes and is distributed mainly through the dispersal of garden waste. It forms dense clumps, spreads rapidly and will dominate the local flora. Although now widely distributed, introductions into new areas could be prevent by gardeners and horticulturalists adopting the Be Plant Wise guidelines.
