Abstract:
Perennials are mostly herbaceous plants, which outlast the winter season with the help of storage organs. In case of their majority, aboveground parts die off during winter. Due to this phenomenon perennial borders look rather unattractive in winter. Dry, dead parts of plants and underground dormancy of several species may often cause an unwanted appearance in plantings. The research topic of this Master´s thesis focuses on landscape architectural possibilities of perennials´ best use during their time of dormancy. Analysed are the appearance and life of perennials during winter; besides biological backgrounds, functional, ecological and aesthetic aspects are also studied. The study clarifies the principles of perennials´ living as well as their manner/behaviour in winter, using the method of secondary description, based on latest literature. This research is followed by the analysis of the current assortment of a representative Austrian plant trading, examining perennials concerning their physical and visual effects in winter. Research results are: the explanation of different plant-strategies regarding adaption to it´s environment; correlation between geographical location, lifelength and habit of growth (which may remain in some cases also during winter), furthermore the vegetative and generative propagation of perennials, the morphological evolution of certain plant parts, like seedheads and leaves, which may ornament during the cold season. As a synthesis, the aesthetic relevance of different perennials according to their growth strategies is presented. After the analysis of the species, plants are classified into groups of similar appearance. Finally, beyond visualisation, several recommendations for planting composition are created. The lists of plants with winter-curiosity and the recommendations of composition possibilities create principles of design, induce inspiration and may be used as basis for further planning.
