Massive, fast-growing, drought-tolerant succulent tree Euphorbia from southeastern Africa. Easy to start from cuttings, also grows well from seed. Think twice about putting it in the ground where space is limited, near structures which may be damaged by falling branches, or where safety is an issue (eg. lots of foot traffic, kids & pets). Old plants may reach 30 feet or more tall.

Here in the mild climate of coastal Baja California, this plant tends to do a little too well, even without supplemental irrigation. As a result of this exuberance it becomes top-heavy and drops branches, requiring attention and cleanup after storms. If you spoil the plant, this problem only gets worse. On the up side, there are always abundant cuttings around to start new plants.

Exercise caution when pruning or handling this plant. Wear gloves and use eye protection when sawing or cutting. Like other Euphorbias this plant contains a fairly noxious sap. Some people seem immune to it, others can develop a nasty rash, especially when the skin is broken. The spines of this plant are not much of a threat on their own, but can be fairly dangerous combined with fresh sap.

Also a well-behaved container plant, will need to be periodically restarted. Flowers attract great swarms of flying insects.

Stumps may branch at the base to form new plants. Plant is self fertile and produces lots of seed, so volunteer seedlings are not uncommon underneath.
