Donald's crown cactus


The Rebutia fiebrigii 'Donaldiana', commonly referred to as simply Donald's Crown Cactus, is a small, globular cactus that often grows in clusters. Its rich green body is comprised of many spiraling ribs adorned with areoles from which emerge small, fine spines that can range from white to yellowish in color. The spines are generally short and form a dense, protective layer over the cactus. During the blooming season, Donald's Crown Cactus is known for its vibrant and eye-catching flowers. These flowers are large in relation to the body of the cactus and come in a stunning orange to red color. The petals of these flowers are numerous and form a funnel shape, providing a striking contrast against the green of the cactus body. The plant's surface texture is rough due to the presence of spines and ribbed contours, while the flowers have a softer, delicate texture. The overall appearance of Donald's Crown Cactus with its flowers in bloom is quite exquisite, making this plant a favored choice for cactus enthusiasts and those looking for an ornamental plant with a dramatic flair.

  • water dropWater

    For the Crown Cactus, watering should be done sparingly. It is best to allow the soil to dry out completely between waterings. Typically, you might water your Crown Cactus once every two weeks during the active growing season, giving it about 4 ounces of water each time, depending on the size of the pot and the environmental conditions. During the winter dormancy period, reduce watering to once a month or less, ensuring that the soil remains dry for longer periods to prevent root rot. Never let the plant sit in water, as this could lead to fungal issues and potentially kill the plant.

  • sunLight

    The Crown Cactus thrives in bright, indirect sunlight. Placing it in an east or west-facing window where it can receive plenty of light without being exposed to the harsh midday sun is ideal. Avoid placing it in full shade, as insufficient light can stunt growth and reduce flowering.

  • thermometerTemperature

    The Crown Cactus prefers temperatures ranging from 50 to 75 degrees Fahrenheit but can tolerate a brief dip down to 40 degrees. Avoid exposing the plant to temperatures above 80 degrees, as this can cause stress. The ideal temperature range for promoting growth and flowering is between 65 and 75 degrees Fahrenheit.

  • scissorsPruning

    Pruning of the Crown Cactus is not typically necessary, as the plant maintains a compact size. If desired, removal of dead flowers or damaged spines can be done using tweezers or a soft brush. The best time for any pruning would be after the flowering season, usually in late spring or early summer, to ensure the plant remains healthy and well-shaped.

    Crown Cactus prefers a well-draining soil mix with sand and pumice to promote aeration and prevent root rot. A common recipe includes one part potting soil, one part coarse sand, and one part perlite or pumice. The ideal soil pH for Crown Cactus should be slightly acidic to neutral, ranging from 6.0 to 7.5.

  • plantRepotting

    Crown Cactus should be repotted every two to three years or when it has outgrown its current pot. This helps to refresh the soil and give the roots more space to grow. Repotting should be done in the spring or early summer when the plant is actively growing.

  • circleLife cycle

    Rebutia fiebrigii 'Donaldiana', commonly known as Crown Cactus, begins its life cycle when a seed germinates in well-drained, gritty soil under warm conditions with indirect light. As the seedling emerges, it develops primary spines and starts to form a small globular green body, characteristic of juvenile cacti. Over several years, the Crown Cactus grows, reaching maturity with a fuller, round body covered in dense clusters of spines and typically flowering in the spring or early summer, displaying vivid orange or red flowers. Flowers are pollinated by insects, leading to the production of fruits that contain seeds, facilitating the spread of the plant in its habitat. The mature Crown Cactus may also produce offsets or "pups" around its base, which can be detached and planted to propagate new plants asexually. As the plant ages, it continues to flower annually, with the potential to live for many years in the right conditions before eventually dying back.

    • Propogation time


    • The most popular method of propagation for the Rebutia fiebrigii 'Donaldiana', commonly known as Crown Cactus, is through seed sowing. Seed propagation is best done in the late winter to early spring when temperature and light conditions are favorable for germination. To propagate Crown Cactus by seed, one would first need to obtain ripe seeds from a mature plant. These seeds are then sown on the surface of a well-draining cactus mix and lightly covered with a layer of sand or fine grit. The container with the seeds should be kept moist and placed in a warm spot with bright, indirect light. Germination usually occurs within two to four weeks. The seedlings can be transplanted into individual pots when they are large enough to handle.
