ISU Trials and Awards 2024

Dear Sir or Madam,

From now you can apply for the ISU-trials in 2024 at the KVCB in Angers, France. Originators and holders of new cultivars are kindly invited to send in their new introductions for evaluation. As 2022 for the first time, now also non-ISU members can also submit their novelties. The requirements for participation to the evaluation of new introductions in 2024 we explain in added documents "Evaluation Awarding ISU-Perennials - Rules".

Experience learned us: Send in application forms and photos before the plants. Only with this info we will continue!
The application form for the evaluation of new introductions 2024 is since now to undertake online (see below). You will get a confirmation mail with your given information.

Also the president of ISU trial commission, Jonas Bengtsson, the responsible coordinator in Houten, Ronald Houtman and the secretary of ISU, Tina Banse, will get your application.

Do send in your information with the application form below and pictures before 15 May 2023:

Please send in five of each variety plants in normal size, not young plants from plug trays before 30 May 2023 to:

A l'attention de Mr Christian Crépin
ISU plants
Pépinière Lepage
Chemin du Portu
49130 Les Ponts de Cé

The evaluation is going to take place in the same area as the ISU Summer Days 2024.

ISU members can still send in their plants and have them evaluated free of charge. However, we would be happy to receive a donation about 60 €. Senders who are not ISU members can for the first time send in new perennials for evaluation this year for a fee of € 150 per submitted variety.

The ISU-Summer Days 2024 will take place in France from 11 August to 15 August 2024. ISU-members will receive the programme in the beginning of 2024.
Good luck with your participation!

Kind regards

Jonas Bengtsson
President of ISU-Trial Commission
