of Cacti and Succulents.


Rebutia krainziana has very nice red flowers

 

This plant flowers consistently and prolifically.
 


A rare yellow flowering specimen and (Right) the white flowering var. albiflora.  The "normal" and more frequently seen form has bright orange-red flowers, but colour variations of ranges in shades from dark red,  to orange, yellow to pure white.

.
 


Cultivation:
Full sun to light shade.  Water regularly in summer but do not over-water. Keep dry in winter.  Hardy down to -4C.
It is better that they be repotted regularly. Repotting will increase the number and size of stems, and will increase the number of flowers produced.  Repot yearly until it reaches about 100 mm in size, then every two or three years will suffice.  Repotting is best done at the end of winter, but it can be done at other time, too. Do not water for a couple of weeks after repotting, in order to reduce risk of root rot via broken roots.

Propagation: Offsets, seeds

The "normal" form has bright orange-red flowers, however other flower colours have recently been seen on the market.  The new flowers form ranges in shades from dark red,  to orange, yellow or white, and at first they were thought to be hybrids, but they also could be simply natural colour variations.
