Mammillaria subducta

It always blooming in late winter and early spring here, in California

Rebutia fiebrigii

This plant always blooms through the winter, when greenhouse does not get that hot on sunny days. It does not produce spectacular shows of tens of flowers opening simultaneously, like it does in the spring. Instead, at any winter day it has two or three new flowers open.

Matucana haynei

First blooms on this young plant.

Stenocactus crispatus
