Today I brought some crocus pots into kitchen to forth flowers open and to pollinate them. Afterwards they were replaced back to greenhouse.
In this entry crocus species labelled as demirizianus. It was collected by Ibrahim with already ripe seeds in February, so blooming in December could be natural. And I can't exclude that it is another one autumn blooming annulate species, but I have only 3 plants, so before increasing I don't want to make herbarium and dissect plants for description.
