bristle-cluster crown cactus


Rebutia glomeriseta, commonly known as Crown Cactus, is a small, globular plant native to high altitudes in South America. It is characterized by its tight clustering habit, with multiple offsets creating a cushion-like appearance. The plant has a lush green color, with the body covered in white, fluffy spines that give it a soft, downy look. These spines also serve to protect the plant from intense sunlight and to collect moisture from the air. The Crown Cactus produces vibrant, funnel-shaped flowers that come in various shades of orange, red, or pink, which contrast beautifully against its green and white background. The flowers typically bloom from the base of the plant or between the clusters, adding an eye-catching pop of color during flowering season. Its overall look is of a dense, woolly clump adorned with occasional bursts of vivid floral hues, making it a popular choice among cacti enthusiasts and a charming specimen in rock gardens and indoor plant collections.

  • water dropWater

    For the Hedgehog cactus, water approximately every 7-10 days during the active growing season in the spring and summer, allowing the soil to dry out between waterings. In winter, reduce watering to once a month, or whenever the soil is dry to the touch, to reflect the plant's dormant period. When watering, provide enough water to saturate the soil, which typically would be around 8-12 ounces for a small to medium-sized pot. Never let the cactus sit in standing water as it can lead to root rot.

  • sunLight

    The Hedgehog cactus thrives in bright, indirect sunlight. It's best positioned in a spot where it can receive several hours of sunlight daily, such as a south or east-facing window. Avoid direct hot summer sun which can scorch the plant. Providing the right amount of light will encourage better flowering and healthy growth.

  • thermometerTemperature

    The Hedgehog cactus prefers temperatures ranging between 50°F and 80°F. It can withstand colder night temperatures down to about 40°F but should not be exposed to frost. The ideal growing conditions include a warm environment during the day and a slight drop in temperature at night.

  • scissorsPruning

    Pruning the Hedgehog cactus is typically not necessary due to its compact growth habit. However, if any dead or damaged spines or plant parts are present, they can be gently removed to maintain a neat appearance. The best time for this light pruning is in the spring, before new growth begins.

  • circleLife cycle

    The Rebutia glomeriseta, commonly known as Crown Cactus, begins its life cycle when seeds germinate in warm, moist soil conditions. Seedlings slowly emerge with small, green, and globular bodies equipped with tiny spines, requiring bright light but protection from intense direct sun. As they mature, these cacti develop into dense clusters of small, round stems, often producing vibrant orange to red flowers in late spring to early summer. Following pollination, which is typically facilitated by insects, the flowers develop into small fruit bearing seeds for the next generation. Over the years, as they reach maturity, Crown Cacti can produce an abundance of flowers annually, while the parent plant continues to grow and may also produce offsets around its base. The plant can live for many years with proper care, experiencing a period of dormancy in cooler winter months which helps initiate the flowering cycle.

    • Propogation time

      Spring-early summer

    • Propogation: The Crown Cactus, Rebutia glomeriseta, is generally propagated during its active growth period, which is in the spring and early summer months. The most popular method of propagation for this species is by offsets, which are the small cacti that form at the base of the parent plant. To propagate Crown Cactus by offsets, allow the offset to form a callous for a few days after separating it from the parent plant. Then, plant the offset in a well-draining cactus mix, ensuring the soil is slightly moist. Place the pot in a bright, indirect light area and avoid watering it for a brief period, usually a week, to prevent rot and encourage root development. After the new roots have formed, typically observable in a few weeks, care for the young cactus as you would a mature plant, slowly acclimating it to more direct sunlight.
