Mammillaria carmenae  is one of the most beautiful species, with creamy flowers blooming abundantly from late winter to early spring.
This plant is nowadays available in different spination colours, ranging from white to brownish-red.  

 

 

 

 

Cultivation: It is a  relatively rapid growing  species.  This is easily grown into clumps, but it does often have an irregular pattern of offsetting.  Water regularly in summer, but do not over-water (rot prone).  Use a pot with good drainage and a very porous potting media.   Keep dry in winter.   Feed with a high potassium fertilizer  in summer.   It is quite frost resistant if kept dry, hardy as low as -5° C. Outside full sun or afternoon shade, inside it needs bright light, and some direct sun.
Easily clustering and easily flowered.
 Most plants will offset readily, and clumps can be produced in a few years.

Propagation: By division, or direct sow after last frost.
