Cactus / petinifera

The flower of Uebelmannia is very small.
The photo is a Uebelmannia pectinifera v multicostata which I bought seeds and sowed in 2005.
Just one small flower opened.

Cactus / pectinifera

A mammillaria pectinifera pushes flowering buds up.
Although it is mid of winter, spring will be soon.
I have propagated this one from seed.
