It is diminutive relative of C. laevigatus from Crete. Like all the species that enter winter with well-developed leaves, here it can be grown only under cover where it perfectly blooms usually starting from the end of October (although the earliest record is from 5th October, 2011) and finishing in December. C. pumilus is reported as sufficiently hardy, but here in our long and as a rule harsh winters it can suffer from frosts. It very well sets seed and multiplies by corm division.
