ONCE EVERY 10 YEARS, →
gardeners, urban planners and plant enthusiasts from around the world come together for Floriade, an international horticulture exhibition in the Netherlands. This year’s festival takes place from April 14 to October 9, and 40 countries have signed up to host pavilions that show off their local plants, as well as trade solutions they’ve found to make their cities more sustainable. Among the attractions: Qatar’s 3D-printed “Desert Nest” and Germany’s water playground. After checking out the sites and walking through the Dutch arboretum, visitors can ride a cable car over the grounds for views of the sprawling gardens below.
