Ecological roses-a possible alternative for modern Romanian landscape architecture (in English)

This paper is referring to several ecological roses which are relatively recently introduced in Romanian rose collections. These roses have a high hardiness and a good diseases resistance and they have to be pruned only once every 4-5 years. Therefore the environment damages are low (less pesticides are used; they can be planted on slopes and can prevent the soil erosion and landslide). The paper is referring to the behaviour of ten varieties of groundcover roses under the climate conditions in Cluj area and tries to extend the interest of Romanian landscape architects, designers and producers in using groundcover roses.
