REBUTIA. "Pigmy Cactus" are tiny South American 
cacti noted for their profusion of brilliantly colored 
flowers, ranging from yellow to orange and red. One

reasonable amount of moisture during the summer, but 
keep them cool and drier during the winter months. 
Suitable for tiny pots or bowls since they seldom grow 
more than one or two inches in diameter after which 
they usually form small clusters. The rarer and more 
difficult kinds are offered as grafted plants, the stocks 
of which need more root space than those on their 
own roots.
