Also called the Fishbone Cactus, this popular orchid cactus has long, flat, succulent green stems that form a zigzag. Stems are spineless; they start growing straight but eventually trail down, making the ZigZag ideal for hanging baskets or pedestal planters. Plants are easy keepers, requiring a few hours of moderate light during the summer, full sun in winter. After a few years, magnificent, scented white or pale-yellow blooms will appear, opening for one night only. If you’re lucky, you’ll get a few small kiwi-like fruits too. Delicious!
