Pedilanthus Pavonis is commonly known as the peacock's tail plant due to its striking leaf patterns that resemble the feathers of a peacock. However, there are several other synonyms for this plant, including Euphorbia pulcherrima var. punicea, Devil's backbone, and Slipper plant. Devil's backbone refers to the unique shape of the plant's stem, which resembles a backbone, while Slipper plant is a nod to the shape of its flowers. Euphorbia pulcherrima var. punicea is another name for the red poinsettia, the plant's close cousin with similar red leaves. No matter its name, Pedilanthus Pavonis is a stunning addition to any garden or indoor plant collection.
