This Harlem rooftop garden is the perfect sanctuary for relaxing or entertaining. It features an ipe pergola with wisteria vines growing up the posts that will eventually cover the top in prolific spring blooms. Ipe (pronounced e-pay) is a hardwood with a 40+ year life expectancy. It can be oiled to bring out the rich reddish-brown tones, or it can be allowed to weather to grey. Additional plantings include coralbark maples, cherry trees, and arborvitaes.
