Cactus / Suguri Cauliflower

This is Ariocarpus retusus v furfuraceus cv Sugri Cauliflower.
I bought seeds and sowed on 31/08/2005. I grafted young seedlings and 2 plants were survived furtunately. I collected seeds from these 2 plants and increased numbers. I have another 5 grafted floweing size plants and mored than 100 of own-roots small seedlings. Only 1 plant was in flower this time and I could not cross pollen.
