PERENNIAL DESIGN IN OPEN PUBLIC SPACE IN LOWER AUSTRIA - RESEARCH ON HERBACEOUS PERENNIAL PLANT USE AND PLANTING DESIGN

S. Schwingesbauer, S. Plenk
Perennial planting design in open urban space increasingly results in extensive sustainable planting sites, which are economically efficient and low in maintenance. Therefore claims, as individual approach or aesthetic values in design, can be obtained. Thus an alliance of experts, gardeners and scientists provides a great diversity in naturalistic planting styles with theoretical background and practical experience today. International development of research and practice in planting design corroborates this hypothesis; focussing on Lower Austria and its public green space – it requires an action-orientated consideration to affirm this evidence. From 2008 until 2011 the federal state government (“Aktion Natur im Garten”) assigned a research project to improve the use of habitat related planting design in open public space. The aim of the project was to create a register of herbaceous perennial plants corresponding to different references for planting sites in public spaces for the use in Lower Austria. For every revised planting site there is information available; for example implementation, visual performance, maintenance or optimization of the plant inventory. The planting type “Combination with Herbaceous Perennials and Roses” had the best aesthetic value, but was high in care time. “Planting after levels of Sociability”, a steppe site planting, showed a satisfying balance in between aesthetic impact and low maintenance. However, the type “Planting with Sowing” had a satisfying to good visual performance and is easy to maintain and low in cost. Thus this type will be remarked for further research. The applied register is the first Eastern Austrian data base for this subject and it should support other municipalities in the successful implementation of individual planting sites. It is recommended to continue this research work in 2012.
