| Abstract:
The use of perennials in public spaces has been extensively discussed in recent years. This exercise has involved an active and lively exchange of information and experiences at symposia and in journals. Most concepts pertaining plant use tend to plantings which are economical and require minimal maintenance. Viable solutions include appropriate planting for the selected area, and realistic assessment of maintenance costs. Our conception of planning was decisively influenced by the work of American landscape architects Oehme and van Sweden. We recognised in their way of plant use an opportunity to provide accents through the use of perennials and grasses in public spaces. A special attraction is the contrast between architecture and rich natural vegetation. Through this interaction new pictures emerge in the creative context with the surroundings and attract the viewer as a whole. The planting design is simple and roughly structured, nevertheless it allows a continuity in flowering, and thus a constant seasonal change of appearance of the planting. Relatively extensive plantings of single species are interweaved in a natural way. At any point of time only two to three plants are in bloom. Exactly this restricted diversity produces strong images with good effects, varying over time. The limitation of species numbers implies a stringent selection. Candidate plants must be robust, have long flowering periods, attractive foliage and texture. The design principle can also successfully be transferred to small private gardens by proportionally correct application. This attractive design option can even be a low maintenance alternative to lawn. | |
