Cactus / furfuraceus

I collected seeds of Ariocarpus retusus v furfuraceus cv cauliflower and sowed on 02/10/2010.
24 of young seedlings were grafted on Pereskiopsis stocks.
Some of them, one and  a half yeres old scions were in flower yesterday.

Pereskiopsis stock loses leaves in second winter in my environment and reduced growing speed of the scion significantly. I will degraft all of then next September.
