ABSTRACT
The research was carried out in the period 2013–2015 in Krakow. Its objective was to assess the usefulness of multispecies and multi-cultivars mixture for sodding for extensive green roofs. The blend of scattered stonecrops shoots comprised of 13 species of the genus Sedum were evaluated in terms of selected biometric features Two of them, Sedum album and Sedum spurium, were represented by four varieties each while others – by a single variety. In terms of rooting and wintering, most suitable for multi-species blend used in the early autumn were: Sedum acre, Sedum album Coral Carpet, Laconicum, Micranthum Chloroticum, Murals, Sedum cyaneum, Sedum oreganum, Sedum rupestre, Sedum sexangulare and Sedum spurium Fuldaglut, Roseum. After the first year of research: Sedum ewersii, Sedum floriferum Weihenstephaner Gold, Sedum hispanicum and Sedum lydium disappeared from the mixture. Species with greater mass of the plant, i.e.: Sedum hybridum, Sedum kamtschaticum Variegatum and Sedum spurium Album Superbum and Variegatum Tricolor had difficulties with rooting. Furthermore, their condition in the spring of the second year of the study was defined as very bad, bad, or bad to average and significantly worse in comparison to species with a smaller mass.
