“Orchid Show: Patrick Blanc’s Vertical Gardens”

A madman of the horticulture world brings his gravity-defying floral arrangements to this year’s orchid show. The French botanist designed the show so that blossoms not only sprout out of planters, but also from 13-foot cubes and eight-foot-tall canvases. Learn about the techniques Blanc invented during a Q&A with garden staffers (Sat, Sun 1, 3pm). Or swing by Sat 6:30–9pm ($30, members $20) to enjoy the living installation with a cocktail.
