Criteria for plants on green roofs
Selecting the right plants for a green roof depends on various factors, which must be considered in different manners from roof to roof. Every roof is a little bit different, and so green roofs and their plants differ too. In the case of extensive green roofs, the most important thing is to select plants that are relatively easy to spread, are easy to service and maintain and last but not least, are especially robust. Nevertheless, the plant species and the method of application differ in some factors.
Examples of plants used on green roofs
There is a long list of possible plants for use on extensive green roofs. Despite the extreme site conditions, there are some species that can combat dryness and drought, frost and wind and not only provide an especially beautiful appearance for your roof, but also offer environmental benefits. Species of sedum (yellow stonecrop) belong to the stonecrop family. With more than 420 different species, sedum plants are one of the most extensive genera within the stonecrop family. Along with houseleeks, these species are ideal for green roofs, as they can store water and are largely self-sustaining after a short time and do not require much servicing or work. We use only high-quality sedum shoots and matting in our products, with 5 to 8 different species of plant depending on their availability and the season. In order to be able to provide you, the customer, a simple and convenient solution, we here at TOPGREEN keep ready prepared mixtures in stock, which have been put together in an ideal manner for green roof coverings. The exact composition depends on the availability of plants and the season.
