‘He is truly the German perennial master right now and leads the European Movement for his work on perennial plantings’

—Noel Kingsbury

In his 18 years as Director of Hermannshof Gardens in Germany, Cassian Schmidt remains at the forefront of planting design, developing signature methods and using natural plant communities as models for sustainable, low maintenance plant combinations equally at home in private gardens and public landscapes.

The research at Hermannshof trial gardens includes plant ecology, performance and the coexistence of plants in designed plant communities. These findings are of great interest internationally though climatic conditions in central Europe will normally vary from those in Australia. However, his approach of using natural plant communities as a template for urban planting design can be generalised.

Cassian has developed various strategies for maintenance depending upon planting types. They are based on the survival strategies of plants—for example, plants with stress tolerance.

His research regarding economic yet ecologically based maintenance techniques is critical, since reduced maintenance time and cost without loss of aesthetic values is key to sustainable public greening and will therefore be of great interest for cities everywhere.



In this workshop Cassian will share his extensive knowledge based on his intensive research on the best strategies for reducing the amount of maintenance in naturalistic plantings. Although trialled on perennials growing in a cooler climate than Australia, many findings can be generalised.

Based on 15 years of research on different maintenance concepts for private gardens and public landscapes, the participants will learn about amounts of maintenance per year required for different planting schemes. He will also explore the need for and most effective ways to preserve the ecological and aesthetic qualities of naturalistic plantings.

The workshop will include practical considerations such as soil preparation, advantages of using engineered soils, using organic or mineral mulch layers, pruning times and methods, watering and fertilising regimes.
