Euphorbia ingens (Euphorbia ingens) are large, tree-like succulents that are beloved for their stately appearance and low-maintenance nature. They are characterized by dark green, four-lobed stems and a columnar growth structure that branches as they mature—leading to the common nicknames candelabra cactus and African candelabra tree. As with many other plants in the Euphorbia genus, the Euphorbia ingens grows well both indoors and outdoors and has become a popular choice for rock gardens and indoor houseplant collections alike. In their natural environment, these succulents can grow up to 40 feet tall, but they usually top out at around 8 to 10 feet tall when grown indoors. Growers should exercise caution when handling this succulent tree as the milky latex sap of the Euphorbia ingens is considered toxic to humans and pets.
