  •   Euphorbia mammillaris Corn on the Cob Cactus is a striking succulent euphorbia native to the Eastern Cape of South Africa, where it grows in rocky, arid terrain under intense sun. Part of the enormous Euphorbia genus, this easy-care plant has earned a loyal following among collectors and beginners alike for its unmistakable sculptural form and tough, drought tolerant nature.

      The Euphorbia mammillaris Corn on the Cob Cactus gets its name from its ridged, segmented green stems covered in neat rows of tubercles that genuinely resemble a cob of corn. It grows in an upright, clustering habit, sending up multiple columnar stems that slowly form a dense, architectural clump. Available in 2" and 4" sizes, it stays compact and tidy, making it one of the most visually distinctive euphorbias you can add to a collection.

      Euphorbia mammillaris Corn on the Cob Cactus produces small, inconspicuous flowers at the tips of mature stems, typically appearing in spring and summer.

      Euphorbia mammillaris Corn on the Cob Cactus is a fantastic choice for sunny windowsills, outdoor summer displays, and xeriscape-style container gardens. It survives a 10-day trip alone without any fuss, so it travels well when you order online. Because the milky sap can irritate skin and paws, it is best placed on a high shelf out of reach of pets and small children. This corncob euphorbia is a rewarding, low-maintenance plant that punches well above its weight in character and collector appeal.

    Q: How much light does Euphorbia mammillaris Corn on the Cob Cactus need?
    A: This plant loves bright direct sun and does best in a south or west-facing window, or outdoors in full sun during warmer months. Avoid deep shade, which will weaken the stems over time.

    A: Absolutely. Euphorbia mammillaris Corn on the Cob Cactus is beginner-friendly thanks to its easy care, drought tolerant nature, and forgiving watering schedule. It even survives being left alone for up to 10 days, making it ideal for travelers or busy plant parents.

    🌵 For Succulents
    When your package arrives, you may notice a bit of loose soil in the box. This is completely normal during shipping.
    Please remove your plants from their packaging right away and follow the care instructions included with your order. Succulents prefer to dry out between waterings, so only water when the soil is completely dry.
    Succulents are resilient plants and typically recover quickly once they settle into their new environment. Give them a few days to adjust before placing them in direct sunlight, and avoid fertilizing right away.
