(DC) (National Arboretum) This three-day weekend event is devoted to the Japanese botanical art of kusamono. Discover how wild grasses, wildflowers, and other small native plants may be artistically arranged to suggest miniature representations of natural habitats. Often displayed alongside bonsai as an accent, kusamono stands on its own as a complete expression, emphasizing simplicity, seasonality, and a sense of place. Come see the exhibit and watch free demonstrations every day in the museum’s Exhibits Gallery. Buy kusamono plants, soil, and ceramics from vendors on the East Terrace.
