BONN, Germany: Over 60 new perennials have been planted and evaluated in Great Dixter since 2014. The nine-member international ISU commission for plant analysis examined the perennials on 10 August.

Xavier Allemann, President of the ISU commission for plant analysis thanked Linda Jones, who supervised the planting as an experienced expert analyst, and Fergus Garrett, the Head Gardener, for the care and pre-selection of the plants in the “Mecca for Gardeners”, Great Dixter.

The six outstanding perennials proved themselves on the difficult clay soil in Great Dixter and were in a very good condition in August. Therefore the jury is also expecting good further development of the plants. During the presentation of the awards the three prize winners Jan Spruyt, Tomasz Michalik and Graham Spencer emphasised that their plant breeding objectives are plants particularly suitable for the garden, which can be used successfully by landscape gardeners and satisfy the end customer in the long-term.

Jonas Bengtsson, Swedish representative in the ISU commission for plant analysis for many years, was elected President of the Commission and is the successor of Xavier Allemann.
