Notocactus cupreatus/luteoroseus
n.n.
Notocactus roseoluteus was known by
the provisional name Notocactus cupreatus.
Remarks:
This plant seems to incorporate some
of the features of both
N. herteri and
N. mammulosus. Both flower
colour and spination seem to be midway between the two species. The
plant can ultimately reach the size of
Notocactus herteri
but it flowers at a much
smaller size and withstands some winter coldness.

Cultivation: Suitable for the home or a greenhouse, During
winter's rest period they should be dry and cool, it is frost
resistant to -4°C but thrives best with additional heat, 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, rot
easily if the substrate is wet and cold. Prefers filtered bright light
with ample airflow. Will enjoy regular water in summer. Best if watered with rain water, an acid
compost and iron feed help to delay the onset of basal corking. A well
grown plant is a fresh glossy grass- green, contrasting with reddish
spines.
Reproduction: Usually by seeds as it seldom
produces offsets.
