To observe growing in their adopted habitats all 165 currently or formerly established aliens recorded from Shetland, all of which have been observed as indicated. Many are common and widespread and include well-known garden plants such as bluebells, daffodils, montbretias, and the increasingly popular early pampas-grass. Others, however, have declined markedly to the point of now being very scarce, nearing extinction in a few cases, or not now eligible for inclusion under this heading. These are all marked by an asterisk. Project completed.
