Landscape architecture is a multidisciplinary branch based on the principle of conservation and / or re-creation of ecological balance. Landscape design is the fusion of both living and inanimate material based on this principle. The plant material, which is absolute for ecological balance, is classified hierarchically and used in the form of trees, shrubs, climbers, groundcovers and turf groups.Within this structure, grasses constitute a group which is relatively new and infrequently used in Turkey. Grasses -the group of plants that develop mainly in ground covering or bushy form -are ecologicallyprominent,due to low water consumption anddesign prominent, due to contribution to landscapecolour and motion.
In this research, 21 species and its 14 cultivars of 10 grass genera,Acorusgramineus ‘Ogon’ and ‘Variegatus’; Carex comans ‘Bronze’; Carex morrowii ‘Ice Dance’; Carex oshimensis ‘Everest’ and ‘Evergold’; Carex testacea;Cortaderia selloana ‘Gold Band’ and ‘Silverstar’; Leymu sarenarius; Liriope muscari and L. muscari ‘Variegata’; Miscanthus sinensis ‘Flamingo’ and ‘Zebrinus’; Muhlenbergia capillaris; Ophiopogon japonicus and O. japonicus ‘Variegatus’; Pennisetum viridescens; Pennisetum setaceum ‘Rubrum’ and P. villosum with Stipa tenuissima, were observed over a four season period in Aegean climatic conditions; in this process, the plants’ adaptation to the area together with the visual changes they demonstrated were examined.
As a result, among the grass group plants sold for the landscape sector in the Bayındır district of Izmir, the species which provided open field adaptation and avoided visual deterioration were determined. Therefore, a guiding source has been produced for compatible grass species and their visual characteristics which can be used in landscape designs in Aegean and Mediterranean climates.
In this direction, it is aimed to spread the use of grasses in order to protect the water regime, increase biodiversity and expand the visual richness of landscape designs.
