Botanical Excursions

The excursions of the International Perennial Society (ISU) have a long tradition. Since ISU foundation there have been several excursions. They either go to botanically interesting regions and give good inside view of our perennials in the wild, or the program is dedicated to garden culture, visits to interesting parks and gardens as well as to botanical gardens.
On these ISU excursions plant and garden enthusiasts meet each other, friendships are made and maintained.

 


 Excursion to the Slovenian high karst 2025

Review of the excursion to the Slovenian high karst 2025
16. JUNE – 20. JUNE 2025

 

Thomas Ster, former director of the Botanical Garden in Graz, knows the Slovenian high karst well from many hikes and guided the participants of the ISU excursion 2025 unerringly to interesting sites. His list of botanical treasures that could be seen during the ISU excursion is long and was sent to all participants.
