Zigzag Plant, commonly known as Devil’s Backbone, Redbird Cactus, Bird Plant or Redbird Spurge, is a distinctive ornamental foliage plant recognized for its unusual zigzagging stems and attractive leaves. The plant has traditionally been sold under the botanical name Pedilanthus tithymaloides. Current botanical references, including Kew, treat that name as a synonym of Euphorbia tithymaloides. It belongs to the Euphorbiaceae family.
