    Stick-like succulent that can grow to be a large tree in permissive climates (beware, cold sensitive!). Easy to start from cuttings but handle with great care as the sap is a nasty irritant (use gloves, sharp tools, eye protection). Needs strong light to do well... will stretch and droop in low light. Like other tree Euphorbias it will drop branches during strong wind events. Old trees run an increasingly high risk of falling over under their own weight.

    It also does surprisingly well in containers, and the stick-like juvenile form can be grown as a miniature. There are orange and red versions of this plant (common name "Firesticks") which have much more ornamental appeal and do not usually grow beyond the size of a large bush.

    Very easy to propagate, but beware if you plant it in the ground. In a favorable climate, E. tirucalli can grow very large and spread quickly. The plant is then prone to breaking and falling apart in the wind and can make a colossal mess in a garden.
