This nighttime event, held across the grounds of the Arcadia botanical garden, returns for its second year with two additional themes: “polar dreams” and “ocean visions.” Last year’s debut included a slew of Chinese lanterns—but not the small, hanging type—that covered a field at the Arboretum with parade-float–sized structures, with other themed archways and playful creatures lining the pathways around the grounds. The lanterns, crafted by artisans from China’s Sichuan province, are arranged by their themes; this year’s pair of new themes should bring penguins, sled dogs, fish and sharks into the fray.
