(Crocus biflorus nubigena)
A variable species (newly elevated from a subspecies of biflorus), this hails from western Turkey. It makes numerous, narrow leaves and a stunning display of flowers, several per corm, each with a white or pale blue-lilac ground colour overlaid with dark stripes or speckles on the outside.
The anthers are a very striking jet-black before they ripen and are notably long. The subsequent pollen is yellow, the anthers being set around a yellow-orange style..
Rarely offered and never common, but readily grown under standard Crocus conditions. This makes one of the best displays per corm that we know of.
