Plant Description:
This is the striking red-leafed and variegated rubra form (‘forma’) of the African Milk Tree, but please note that the red fades to more green shades over winter when it enters dormancy.

This species can grow to 3-4 m high over tten years or so.

While this looks like a cactus (family Cactaceae), it is actually a Euphorbia from the Euphorbiaceae family.

The fourth photo shows the milky latex sap which is endemic to all euphorbias, and which is toxic. The sap in this photo was from me handling it a little roughly on repotting — it does NOT exude this sap unless cut. I photographed it just so you know what to look for. The sap can cause skin, eye and mouth irritations so exercise care and avoid contact, and both you and it will happily live side by side, as it requires very little care!

Growing Information:
Euphorbia trigona f. rubra is a low-maintenance plant which is suited both as a houseplant and outdoors. Growth may be slower indoors. The milk tree can withstand brief exposure to temperatures as low as -3°C, but would be best inside in cold winter climates.

E. trigona is somewhat drought-tolerant, but does still require weekly watering — it may look like a cactus but is very much not a cactus.

This is not a child- or pet-friendly plant on account of the spines and irritating latex sap. This sap is not of concern unless the tree is cut, and even the slightest abrasion will cause the sap to appear immediately. The sap in the fourth photo appeared just from the tree rubbing against an object I had leant it against prior to repotting.

E. trigona can be propagated from stem cuttings which have been left to callous over a week.
