Hi Ebo,
Welcome to the forum!
Dad grew a cultivar of that name, some time last millennium…. My principal memory of it was that the flower was quite unlike any other humilis, being held well above the compost on a decent, upright stem. I seem to recall that the bulbs, tho’ having the same overall shape as yours, were ribbed. Also the bulbils were numerous and tiny.
I think I’ve got a photo of it, back in the archives, probably on slide, but finding it would be a ‘needle in a haystack’ job! I need at least three reasons to go digging into the old photo collection, but next time I do I’ll keep an eye out for it.
Incidentally, Dad reckoned that his clone was probably a hybrid. It wasn't vigorous, and I don't remember ever seeing more than one flower at a time.
