Euphorbia Leuconeura (Madacascar Jewel Plant): How to Grow Care

I was given a houseplant with a unique, square stem. New leaves come from the top of the plant, and it has small white flowers that appear at the base of each leaf where the leaf joins the stem. Any idea what this is called, and how I should look after it? Thanks!


Hi Olga,

Your plant looks like a Madagascar Jewel Plant (Euphorbia leuconeura). Here are some care instructions on how to grow a Madagascar Jewel plant as an indoor houseplant.

Light: bright indirect light, no direct sun.

Water: Water once a week in the spring and summer when the plant is actively growing or when the top 50% of the soil has dried out. Water every other week in the fall and winter or less if the soil has not dried out.

 Feed monthly with a plant food for succulent plants when your plant is actively growing.
Propagation: With proper care, these plants literally spray their black seeds all over the soil.
Euphorbia leuconeura are considered poisonous and should be kept away from pets and children. Handling the plant, especially the sap, can cause skin irritation or allergic reaction.
