I discovered these large, pink flowers on short stems in my neighbours "lawn" (a pension which is closed for the season), and I suppose are Zephyranthes sp. as well, from what I have read here. I don't know the species or variety, what do you suggest? I remember they had some flowers which probably were of the same in a flower box on on of the balconies several years ago, when I asked what they were, the answer was κρίνοι (lilies). Some seed have fallen down on the ground below, where I found the flowers, I'll see if there any seeds before I leave Greece next week.
