Description

Euphorbia tirucalli is a succulent, spineless shrub or tree with a heavy trunk, brown primary branches, and pencil-like, green, new branches. Leaves cluster at the tip of the branches, as do insignificant flowers within showy bracts. It is tropical to semi-tropical by nature and reliably winter hardy to USDA Zone 11. It is currently surviving in southern parts of Florida and California in Zone 10. It is drought tolerant and when grown outdoors in warm climates, the tree can reach heights of 30 feet and is typically used as a hedge or barrier. When grown in more temperate climates, it can be kept smaller and used as a houseplant.

When grown outdoors, plant in well-drained soils that are nourishing but without high organic content. When grown indoors, use coarse loams with peat moss or leaf mold plus gritty material such as coarse sand.

The plant has a low-level toxicity that, when plant parts are ingested, can cause nausea, vomiting, or diarrhea. The sap of the plant when in contact with skin can cause redness, swelling, or blisters for a short duration and with some delay after initial contact.
