  • Abstract in English : In the UK, the concept of the extensive green roof has only recently received attention. Where green roofs have been implemented, the tent to be systems important from Germany and are generally based upon prefabricated sedum mats. There is very little awareness of other potential vegetation types for green roofs. There is, however, great potential in the UK for exploring a wider range of planting and ecological options. This is partly because the relative cool and wet climate may allow a wider range of plants to be grown than is possible in a continental climate, and partly because of the horticultural and gardening tradition of the country. A series of trials is described that attempted to explore the horticultural opportunities in the British climate. A range of different ‘indicators’ drought tolerant plants (creeping plants, clump forming perennials, grasses, and taller emergent species) were established in substrate depths of 100 mm or 200 mm, with or without limited supplementary irrigation.
