Euphorbia trigona rubra - African Milk Tree
This is an easy plant which grows in a tall column and will add many upright branches over time. The leaves and stems are flushed with brilliant red.
Your plant will be similar to the one in the photos.
Ships in a plastic pot with soil.
Not as picky about soil, store bought succulent mix is good, especially if you add some sand or perlite/pumice to make it drain a little better
Part sun, protect from hot afternoon sun
Let dry between watering, water deeply
