By the way, it is a very small flower (compare the proportion with the other small plants in the background!) As far as I read, A. fisulosus could grow up even to 70 cm. This plant is very small.
I support Asphodelus tenuifolius - but the fact that A. fistulosus CAN grow up to 70 cm doesn't mean that it necessarily DOES. I have seen them as small as 20 cm in the semi-desert in Tunisia, and then the species are hard to tell apart.
