Euphorbia trigona 'Rubra' has many common names. Milk Stripe, African Milk Tree, Mottled Spurge, and Dragon Bones tree. All these names refer to the upright growth and milky latex sap that Euphorbia exudes when cut. Euphorbia trigona Rubra has red stems that grow out of the main stem, giving the whole plant the look of a difficult-to-grow cactus. The thorns are the modified ‘leaves’ of the plant. This is an easy-to-grow succulent that can be grown outdoors from USDA zones 8a (with winter protection) to 11. 

Best Locations For Growing Euphorbia Rubra

Euphorbia is a plant that demands to be seen and makes a great statement in the corner of a room or hallway. As the plant matures, it can be propagated easily, increasing how densely it grows in a pot. Caution should be used in growing this plant near pets and children. The latex sap is toxic and can cause contact burns or poisoning.

Euphorbia Rubra Sunlight Requirements

Growing indoors, Euphorbia prefers bright indirect light. South and southwest-facing windows are ideal. Euphorbia growing outdoors will need partial shade and protection from the direct sun during the middle of the day.

Euphorbia Rubra Care

This succulent needs free-draining soil that is loose and lightweight. The pot needs to have excellent drainage holes. The roots of Euphorbia Rubra are very shallow and small compared to the overall height. Staking may be necessary to help the main stem stay upright, and planting into a low, wide pot will help counteract any top-heaviness. Euphorbia is easily multiplied by replanting any of the leaf-shaped branches directly into the pot. Always wear gloves when doing this to protect from thorns and latex sap. 

Watering Euphorbia Rubra

Water when the top 2-3 inches of soil have dried. Always discard any water collected in a saucer or cache pot. Euphorbia does not like to sit in water. Humidity levels indoors do not need to be high. High humidity will stress Euphorbia and leave it vulnerable to pests and fungus.

Feeding Euphorbia Rubra

Fertilizing is only needed during the spring and summer when Euphorbia is actively growing. Use a dilute liquid fertilizer formulated for cacti and succulents. Apply every 3-4 weeks. No fertilizing is needed in the winter.

Plant Shipping

Below are some factors we consider when determining when to ship the plants depending on the timing of the order.

Winter to Early Spring

We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.


If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.

Fall into Winter

We’ll ship plants out all the way up to the end of the fall planting season!


Get your order in early to reserve your plants for Spring planting!

Once your plant is shipped you’ll receive an automated email with tracking information.
