Dear Sir or Madam,

From now you can apply for the ISU-trials in 2026 in Alnarp, Sweden. Breeders and owners of new cultivars are kindly invited to send in their new introductions for evaluation. Since 2022, non-ISU members can also submit their novelties. The requirements for participation to the evaluation of new introductions in 2026 we explain in the added documents "Evaluation Awarding ISU-Perennials-Rules".

Experience learned us: send in application forms and photos before the plants. Only with this information we will continue!
The application form for the evaluation of new introductions 2026 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, Ronald Houtman, the responsible coordinator in Alnarp, Karin Persson and the secretary of ISU, Tina Banse, will get your application.

• Ronald Houtman (info@sortiment.nl)
• Karin Persson (karin.svensson@slu.se)
• Tina Banse (banse@isu-perennials.org)

Send in your information with the application form below and pictures before 15 May 2025:

SLU Trädgårdslab
Växthusvägen 14
234 56 ALNARP
SWEDEN

Please send in five of each variety plants in normal size, not young plants from plug trays before 30 May 2025 to:

SLU Trädgårdslab
Växthusvägen 14
234 56 ALNARP
SWEDEN

The evaluation is going to take place in the same area as the ISU Summer Days 2026.

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

The ISU-Summer Days 2026 will take place in Sweden from 15th to 19th August 2026. ISU-members will receive the programme in the beginning of 2026.
Good luck with your participation!

Kind regards

Ronald Houtman
President of ISU-Trial Commission
