Rebutias are tiny cacti that pro-duce an amazing number of flowers for their size. The low, flattened, globular stems reach no more than 5 cm (2 inches) in diameter but in summer produce a mass of trumpet-like flowers from white to yellow-orange and brilliant red, all around the base of the stem.
General Care: Rebutias are some of the easiest cacti to cultivate and are the ideal plants with which to start a collection. They are happy growing on windowsills in full light and are tolerant of varying conditions. A cool dry winter followed by a warmer and more moist spring and summer are the ideal conditions. The flowers close during the evening but reopen with the next day’s light.
Propagation: Rebutias are easy to raise from seed, germinated in the usual way for cacti.
Pests and Diseases: Mealy bugs and root mealy bugs are the main problems; aphids sometimes attack the flowers.
