Botanical Excursions

The excursions of the International Hardy Plant Union (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.
