Rebutia marsoneri Werderm.
Krainz' Crown Cactus
Rebutia marsoneri is a small and very free flowering cactus, up to 3 inches (7.5 cm) tall and up to 3 inches (7.5 cm) in diameter. The spines are very thin, short bristle-like, flexible to somewhat stout, brownish to golden yellow to white, usually with dark tips, variable in length from 0.1 to 0.6 inches (3 to 15 mm) long and often inconspicuous. It develops a larger crop of flowers from the base of each head. The flowers are bright golden yellow to orange or orange-red, up to 2 inches (5 cm) long and up to 1.4 inches (3.5 cm) in diameter. It is usually one of the earliest Rebutias to flower in spring and has a very long lasting and continuous blooming period.
How to Grow and Care
If you can grow cacti and succulents successfully, you can likely grow the popular Rebutia without too much trouble. Their water and light requirements are fairly typical for many cacti species, including a cooling period in the winter to promote better blooming. Watering should be done carefully, allowing the plant to almost dry out between waterings. It's imperative that the cactus is not exposed to prolonged dampness and sitting water. Never let your cactus sit in a dish of water. For the best viewing, instead of propagating your offsets, let the plant for a large cluster. When it blooms, this will make a truly beautiful display. Lastly, make sure to fertilizer during the growing season for the best results.
Repot as needed, preferably during the warm season. To repot a cacti, make sure the soil is dry before repotting, then gently remove the pot… – See more at: How to Grow and Care for Rebutia.
