research task of the University of Wädenswil (HSW), Switzerland

Dynamics, development, movement and time are the main symptoms of the living world, of life itself. Perennials are plants that embody these properties to a special extent. Thanks to these features, they have earned a bad reputation among designers and gardeners alike. Perennial plantings do not wait even a moment in their original state, they are subject to the rhythm of the seasons, vegetation fluctuations, they are unpredictable, they deviate and are difficult to care for, in short and they are difficult. Caring for them often turns into a hopeless struggle against the natural tendency of the perennial community to constantly change. And so designers prefer to reach for calmer, more adapted representatives of the later stages of succession, woody plants. But why not accept this challenge and deal with the "inconvenience" of perennials and study these properties and use them positively?
