It might be the Zig Zag plant, Euphorbia tithymaloides, though it would have been helpful to see the whole plant as well to be certain. It's a type of succulent plant, but does need watering during the growing season, though relatively sparingly. If you're growing it indoors, it will appreciate sunlight year round except during the summer months. Some information here https://toptropicals.com/catalog/uid/Pedilanthus_tithymaloides.htm. Be aware that the sap of this plant can be an irritant on the skin.
