Blooming season: Spring.
 


 

This variety was called Notocactus purpureus.
The purple-violet flowers are stunning


Cultivation: They like a warm bright location, and do great in partial shade.  Avoid full sun.  During winter's rest period they should be dry and cool.  It is best to avoid any frost, but during the winter the temperature can be as low as 2 C without any harm, as long as the compost is very dry.  They like only a short winter's rest.  If the soil is allowed to be dry for too long, root loss could follow but equally the same result would occur if the plants are both wet and cold. Cold spots can mar its epidermis  in cold damp conditions. They need good drainage and prefer a neutral to slightly acidic compost with plenty of extra grit and iron feed help to delay the onset of basal corking..  Water and feed during the summer.  Best if watered with rain water and given an occasional tonic of sequestrated iron. A well grown plant is a fresh glossy grass- green, contrasting with reddish spines.
