Longwood Gardens (www.long woodgardens.org) in Kennett Square, Pa., is one of the won-ders of the horticulture world. With more than 1,000 acres in its possession, including some 20 outdoor gardens featuring everything from vegetables to topiaries toflowers, and four indoor gardens containing more than 11,000 different plant types, you wouldn't think there would be much else Longwood Gardens could do to attract the attention of horticulture professionals and the general public. However, a new East Conservatory Plaza has been constructed that is sure to further amaze and intrigue the 750,000 visitors who come to Longwood Gardens every year. Two of the highest profile features of the East Conservatory Plaza are very different (one indoor and one outdoors, one made of turfgrass, the other of ferns), but share one thing in common: they take on the challenge of growing on vertical surfaces.
