  •   Mammillaria glassii is a stunning pincushion cactus native to the mountainous regions of Mexico. This rare silver fuzzy cactus belongs to the beloved Mammillaria genus, known for producing some of the most collectible and easy care cacti in the world.

      Mammillaria glassii displays distinctive silvery-white spines that create a soft, fuzzy appearance covering its compact cylindrical body. This white fuzzy cactus forms tight clustering groups over time, with individual stems reaching 4-6 inches tall and 2-3 inches wide. The dense white spination gives this silver cactus an almost glowing appearance that stands out beautifully among other succulents.

      Mammillaria glassii produces delicate pink to magenta flowers in spring, typically forming a crown around the top of each stem when mature. The blooms appear after the plant experiences cooler night temperatures during winter months. This clustering cactus releases oxygen at night, making it an excellent choice for bedroom collections.

      Mammillaria glassii makes an outstanding indoor cactus for collectors seeking rare and unusual specimens with beginner-friendly care requirements. This drought tolerant beauty thrives in bright windows, tolerates dry heated air, and can survive a 10-day trip without watering. The plant is pet friendly, making it safe for homes with curious cats and dogs.

  •   Mammillaria glassii thrives in bright indirect light to direct sun, adapting well to various lighting conditions indoors.

      Mammillaria glassii needs deep watering every 2-3 weeks during growing season, less frequently in winter.

      Mammillaria glassii requires well-draining cactus soil mix with added perlite or pumice for optimal drainage.

      Mammillaria glassii prefers temperatures between 65-85°F (18-29°C) and tolerates light frost down to 25°F (-4°C).

These zones include warm-climate states like Florida, California, Texas, Arizona, Hawaii, Louisiana, Nevada, southern Georgia, South Carolina, Alabama, Mississippi, and coastal areas of North Carolina and Oregon.

    🌵 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.
