    Euphorbia lactea is a cactus-like succulent plant with 3 or 4-angled branches that are deeply scalloped and have black spines. It is used medicinally in India.

    All plant parts are considered to be poisonous, especially the white, milky sap which is irritating to the skin, eyes and mouth.

    The plant should be allowed to dry thoroughly between waterings. In the winter months, water should be restricted to once a month in order to avoid plant failure. Rot is the biggest cause of failure in this plant.

    Euphorbia lactea "Cristata" is an intricately monstrous form with fan-shaped crested branches forming a ridge or crowded cluster. The crest form is often used in grafting.
