NEW YORK The New York Botanical Garden's annual Orchid Dinner benefit returned to the Mandarin Oriental on Tuesday night. After cocktails and a sale of rare orchids, about 250 guests entered the hotel's 36th-floor grand ballroom, which was filled with 24 dinner tables designed by floral, event, architectural, and interior designers. Dan Dahl and Veranda magazine oversaw the event. Nearly all of the the tables dripped with the event's namesake flower, but some dominant elements were spotted on multiple settings, such as napkins in bright, preppy prints, contrasting patterns on linens and other tabletop items, and woodsy touches. Here's a closer look at these trends.
