QUALITY GUARANTEED

Euphorbia trigona Cactus commonly known as African Milk Tree, Marble Column or Cathedral Cactus is a real architectural Indoor with upright green stems featuring reddish maroon coloured spines along the ridges of the stems. Each stem is edged with three to four sided oval green leaves when the plant is young before falling away as the plant matures. NOTE: the decorative pot is not included, it will arrive in a 12cm plastic growing pot.

  • The African Milk Tree despite being referred to as a cactus is actually a succulent. This slow growing houseplant can grow to 6ft in height, living for many years with proper care. It is very low maintenance making it ideal for beginners or for plant lovers as a gift, looking great in a bedroom, living room or as a desk or office plant.


  • The plant is known as an African Milk Tree, due to the milky white sap that comes out when it is cut or broken. Please be careful of the sap as it can be poisonous to pets and can cause skin irritation if you come in contact with it.

Please note: the decorative pot shown in the images is for illustration purposes only and is not included with the plant.

Watering Water when the top few centimetres of compost begin to dry, then water thoroughly and allow excess water to drain away. Do not leave the plant sitting in standing water, as consistently wet roots can lead to rot. Growth slows in winter, so reduce watering frequency during cooler, darker months.

Best Growing Conditions Grow in bright, indirect light, ideally at around 18-26°C, away from cold draughts and sudden temperature changes. Use well-drained soil and make sure excess water can drain freely from the pot. Most houseplants perform best with moderate humidity and should be kept away from strong radiator heat.

Top tip

Turn the pot a quarter turn every week or two so the plant develops evenly, and wipe broad leaves occasionally to keep them free of dust. Good drainage is especially important, so avoid leaving the roots sitting in persistently wet or compacted soil.
