Andean ranges of Peru, Bolivia, Argentina and Chile growing at heights of up
to 3000 m (9800 ft).
Description: these plants are typical of mountain cacti, having a
columnar stem covered with dense bristles from which long, different
coloured spines arise. The hairs enveloping the stem act as a blanket that
protects the plant from the bitter cold and the strong solar radiation. They
may have synonyms in Pilocereus, Morawetzia and Borzicactus.

Location: grow young plants in filtered light and adult ones in full
sun.

a dry environment but it’s best to maintain the minimum at around 8° or 10°C
(46-50°F) to avoid the formation of scars.
Water: average.
Cultivation tips: it’s a long-lived, tough genus that grows slowly
and only flowers at maturity.

filtered light in the summer and overwintered at a minimum of 10°C (50°F) to
avoid scars; it resents high humidity; O. hendriksenianus; O. doelzianus
syn. Morawetzia d.;O. trollii; O. variicolor.
