Glandulicactus wrightii
(Syn: Glandulicactus uncinatus)

Glandulicactus wrightii SB840 Cuatrocienagas
Tiny grey stems. Hooked coloured spines.
Frost hardy to temperatures as low as  -12° C.

Cultivation: Somewhat sensitive to overwatering (rot prone) and slow-growing. Grow in a  mineral  cactus compost and provide good drainage. Water in moderation, it prefer a completely dry place during winter. An unheated greenhoouse would be perfect. It can survive low temperatures, approx. -7° (-12°) C. They will do their best with lots of sun and become stressed with inadequate light which could result in poor growth and unnatural shape.  Provide very good ventilation.

Reproduction: Seed.
