Abstract

One type of green roof whose function is ecological and environmentalrather than aesthetic is the extensive green roof. Manystudies have shown that Sedum performs very well compared toother hardy species in substrates of less than 10 cm. It seems thatSedum species are able to survive in very thin substrates; they tolerateextreme temperatures and sudden variations in temperatures,high levels of solar radiation, strong winds, poor substrate fertilityand extreme drought. In particular, this paper looks at the potentialof a number of species from the Sicilian taxa of the genus Sedum(Crassulaceae), which are considered to be those xerophytes mostsuited for use in extensive green roof systems for Mediterraneanareas. Each taxon was subject to in situ and ex situ observations togain phenological and ecological data, information on its vegetativepropagation capacity and its plant ground cover capacity.Theresults of this study have led to greater understanding of Sicilianpluriennal Sedum genus entities of potential use in green roof systemsin the Mediterranean. The taxa respond particularly well toagamic propagation, showing characteristics suited to nursery productionof green roof systems, with the exception of S. amplexicaulesubsp. tenuifolium. Growth indices and plant development(ground cover) demonstrated the capacity of a number of Sedumtaxa to form a uniform green mantle over time. S. sediforme andS. album subsp. album. showed interesting results, for because oftheir ability to colonize the substrate, and they could be fundamentalin determining the plant structure of the green systems. However, there are also other plants, such as S. amplexicaule var.tenuifolium, and, to a lesser extent, S. dasyphyllum var. dasyphyllumand S. ochroleucum, which are able to contribute to floraldiversification and lead to greater biodiversity in the system.These taxa could be used when creating associations of Sedum atlower percentages compared to the structuring species (≤20%).
