It looks tropical and also has a cactus look. 1 inch square stalk, but no spikes or spines anywhere. a small round pod appears and spits small black seeds everywhere. I would appreciate any help you could give to help id this plant Thanks Randy


Hi Randy,

Your plant with the distinctive square stem, is a Euphorbia Leuconeura or Madagascar Jewel Plant. It can grow as tall as 6 ft, resembling a small branching tree. Although Madagascar Jewel plants prefer dry soil, they are less susceptible to over-watering than many other succulent plants. This unique Euphorbia propagates by shooting its seeds into the air and doesn’t mind low humidity. Bright indirect light helps the plant bloom.  When damaged Euphorbia Leuconeura secretes a poisonous white latex sap that causes severe skin irritations so always wear gloves when handling  a Madagascar Jewel Plant.
