I have a plant very similar to yours Chanin. It came with no tag. So far it hasn't bloomed either but its full of plants

There are at least four varieties of Dyckia fosteriana recognized here in Brazil. This species have a less restrictet endemism than we suposed before. There is a particural variety ( natural species in my opinion) that is extremely beautiful: Dyckia fosteriana from Sengés-PR and a small one from Lapa-PR known as Dyckia fosteriana nivosa. It seems some snow have acumulated on top of the plant. This effect is due for the rain. Only the new growth area is scaled in the restant area of the rosette the silver scales are washed away by the rain water.
The result in a Dyckia crossing is always a guessing.So one may do the same and very same cross and experiment other results. Ever and ever all crossing results in Dyckia will be a chance matter.
