The theme of the 2026 event is “Reflections of Nature.” This edition will focus on reflections, contrasts, and dual imagery. Florists, artists, and designers will explore how colors, shapes, and floral creations can enhance one another in installations featuring surprising perspectives and visual effects. According to the organizers, visitors will once again be offered a total experience where nature, art, and heritage come together. The historic Alden Biesen estate serves as the setting for the flower festival, which is open daily from 10:00 a.m. to 6:00 p.m.
