Euphorbia trigona is a perennial plant, up to 9 feet tall. It has an upright stem that is branched into three or four sides. The stem itself is dark green with V-shaped light green patterns. The up to 5 mm long thorns are placed in pairs of two on the stem s ridges. The drop shaped leafs grows from between the two thorns on each ridge. The plant s flowers are white or a combination of white and light yellow. The flowers appear on spring and summer, but potted versions of the plant may not grow flowers at all.
Euphorbias need well-draining soil and lots of sunlight. They are not particular about soil pH, but they cannot tolerant wet soil. Unlike most succulents, Euphorbia does not handle long periods of drought well. It may need weekly watering during the summer. If you are growing them in containers or your soil is poor, feed with a half-strength fertilizer monthly.
