Description
Rebutia marsoneri is a small, free-flowering cactus with globose stems that grow up to 3 inches (7.5 cm) in diameter. Spines are short, thin, flexible to somewhat stout, brownish to golden yellow or white, and usually have dark tips. They are variable in length from 0.1 to 0.6 inches (0.3 to 1.5 cm) long. The plant develops a larger crop of flowers from the base of each stem. 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 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. The cactus mustn't be 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 magnificent 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 cactus, make sure the soil is dry before repotting, then gently remove the pot. See more at How to Grow and Care for Rebutia.
