Establishment and development of ornamental grasses on green roofs and living walls

Abstract Ornamental grasses are often used in gardens to improve biodiversity and as additional aesthetical resources. However, their use green roofs (GR) living walls (LW) is not so widespread it has been studied extensively. The aim of this work assess the performance seven grass species ( Imperata cylindrica ‘Red Baron’ , Acorus gramineus Stipa tenuissima ‘Pony Fails’ Carex flagellifera ‘Bronzita’ oshimensis ‘Evergold’ Uncinia rubra ‘Everflame’ Miscanthus sinensis ) for GR LW. growth plants was evaluated (i.e. biomass production, dimensions), well visual quality survival. C. showed coverage levels greater than 75% good quality, while A. reached 55–60%. I. M. coverages slightly below 50% LW, however, both performed GR, though with a lower quality. U. did develop well, reaching lowest (below 45%) but maintaining high S. also attained low LW presented mortality, especially GR. In stood out flowering, highest flowering rate should be selected considering characteristics order achieve correct appearance development.
