It blooms freely most of the year. It normally becomes dormant in summer… don't throw it away if it loses its leaves. As with the other Euphorbias, its sap is poisonous, it irritates the skin, and can cause temporary blindness if it goes in the eyes.

Trim the stems that are too long, let them dry a couple of day, and stick them into potting medium. They should grow easily if the temperature is hot enough.
