MAMILLARIA 
A genus of small growing cacti low, rounded or elongated, bearing flowers in a circle around the top of the 
stem ranging in color through white, yellow, pink, red or magenta. They are the best adapted to small pot, 
bowl and indoor culture. Small plants are suitable for two inch pots for several seasons or several may be placed 
in a bowl or window box. The bright, shiny, red fruits which burst forth several months after flowering are 
often more attractive than the small star-like flowers. They grow easily from seed and many kinds will mature 
and flower in from one to three growing seasons. When grafted on Cereus seedlings or large Cereus cuttings 
they quickly reach maturity and offset freely rapidly forming large specimen clusters. A collection of this group 
is a source of never ending interest and admiration and is a good one to specialize on as there are several 
hundred species and intergrading varieties.
