Cactus / geometrizans

 It was cold morning. Even in the greenhouse, it was just 4 'C.

I found a Myrtillocactus geometrizans planted in my backyard pushed flowering buds up.

It was North face of the cactus. The North face is warmer in here.

Cactus / kotschoubeyanus

 An ariocarpus kotschoubeyanus f Rio Varde was in flower in this afternoon.

Since winter has been, only limited species are in flower.

It was grafted once and the body has turned to a large block.

Cactus / pectinatus

 I thought it was no more Ariocarpus flowers because winter has been in here but a degrafted pectinatus was in flower in this afternoon.

I got seeds from my friend and sowed in 2018.

12 seedlings were grafted but mice ate scions. As the result, only 3 scions have survived.
