Crown Cactus Rebutia steinbachii
ABOUT
Rebutia steinbachii, commonly known as the Crown Cactus, is a small, clustering cactus known for its vibrant, colorful flowers. The plant has a globular shape and typically grows in clusters, with multiple spherical stems emerging from the rootstock. The surface of these stems is divided into prominent ribs lined with small areoles from which emerge clusters of spines. The spines can range from white to yellowish in color and are quite fine and needle-like, often covering the stems densely enough to give them a somewhat bristly appearance. One of the most striking features of the Crown Cactus is its large, showy flowers that bloom in spring and early summer. The flowers are funnel-shaped and come in a variety of bright colors including red, orange, pink, and yellow. These blooms are significant in comparison to the body of the cactus and emerge near the crown at the top of the stems, hence the common name "Crown Cactus". The contrast between the flowers and the green to a bluish-green color of the stems creates a spectacular display. Despite its small size, Rebutia steinbachii can produce a generous quantity of flowers, sometimes covering the cactus in a colorful floral display. The plant's compact growth habit and the profusion of flowers make it a popular choice among cactus enthusiasts for rock gardens, windowsills, and as a part of small cactus collections.

WaterCrown cactus requires cautious watering to avoid root rot, especially during its dormant winter period. From spring to fall, water only when the soil is completely dry, roughly every 7 to 10 days, with about 8 ounces of water for a medium-sized pot. During winter, reduce watering to once a month, using just enough to prevent the soil from completely drying out.
LightThe crown cactus thrives in bright, indirect light, making an east- or west-facing window an ideal spot. Direct sunlight, especially in hot summer months, can scorch the plant, so a location with morning or late afternoon sun is best.
TemperatureCrown cactus prefers temperatures between 50°F and 75°F and can tolerate a minimum of 40°F. However, anything below freezing can be extremely harmful to the plant. For optimal growth, keep it in a location where temperatures are steady and avoid drafts.
PruningPruning is not typically necessary for the crown cactus as it maintains a compact form. However, if necessary, remove any dead or damaged parts using clean, sharp utensils to prevent infection. The best time for any pruning is at the onset of the growing season in spring.
CleaningAs needed
SoilThe Crown Cactus (Rebutia steinbachii) thrives in well-draining soil mix consisting of a combination of loam, sand, and perlite or pumice to enhance drainage. A slightly acidic to neutral soil pH of 6.0 to 7.5 is ideal for this cactus. Organic matter such as peat or coir can also be added to retain minimal moisture while preventing waterlogging.
RepottingThe Crown Cactus should typically be repotted every two to three years to refresh the soil and accommodate root growth. It is best to repot this plant during the warm growing season when the cactus is actively growing.
Humidity & MistingThe Crown Cactus prefers low to moderate humidity levels and does not require high humidity. It is well adapted to dry, arid environments and can be negatively affected by excessive humidity.
Suitable locationsIndoor
Place Crown Cactus in bright, indirect light indoors.
Outdoor
Grow Crown Cactus in sun to partial shade outdoors.

Life cycleThe life cycle of Rebutia steinbachii, commonly known as Crown Cactus, begins with seed germination, a process that requires well-drained soil and consistent warmth, typically around 20°C (68°F), and can take anywhere from several weeks to months. Once germinated, the seedlings slowly develop into small, spherical cacti through a juvenile phase, characterized by the growth of spines and the initial formation of characteristic tubercles. As the cacti mature, they take on a clumping habit, producing offsets and forming clusters that contribute to their crown-like appearance. Throughout their adult life, Crown Cacti periodically bloom in the spring or early summer, displaying vivid, funnel-shaped flowers, usually in hues of orange, red, or pink, which are pollinated by insects to produce seeds. After pollination, fruits develop, containing new seeds for dispersal, thus continuing the plant's life cycle. The Crown Cactus has a long lifespan and can survive for many years with proper care, often outliving the individual flowers and fruits which are more ephemeral.
PropogationPropogation time
Spring-Early Summer
The optimal time to propagate Rebutia steinbachii, commonly known as Hedgehog Cactus, is during its active growth period in spring or early summer. The most popular method of propagation for this plant is by offsets. Hedgehog Cactus readily produces small offshoots that can be found at the base of the parent plant. These offsets can be gently removed once they are a respectable size, typically a couple of inches across, ensuring a portion of the root is attached. Once removed, it's important to let them dry for a few days to form a callus over the cut surface. This step helps to prevent rot when the offset is planted. To plant, one should use a well-draining cactus mix, and the offset should be placed on the surface, lightly pressing it into the soil. Water sparingly, just enough to moisten the soil without making it soggy, until roots have established, which can take a few weeks.
