Kris, nice to see Crocus wattiorum in so later time.
Tony,
in my observation blossoms Crocus nerimaniae always without foliage, it appears only weeks after the blossom and remains also the whole winter about no longer as 2-3 cm. With Crocus wattiorum the foliage comes by the end of the blossom and grows in mild weather the whole winter. Now Crocus nerimaniae about 2 mm has
long foliage, Crocus wattiorum about 5 cm.
