ISU Summer Days 2024: from production to show gardens

The International Perennial Union offered the almost 60 participants of the Summer Days from August 11-15 in Angers, France, a very diverse program. Perennial experts from 12 European countries and the USA met there from variously structured companies and enjoyed the professional exchange as well as the typical local culture.
