Is the Greek mythology about the early-flowering crocus, hyacinths and daffodils unchanged and authentically / natively Indo-European ? Like all early bloomers, daffodils are a symbol of rebirth, the victory of life over death (represented by winter) and they also had this meaning in pre-Christian Indo-European mythology :
The mythology known today around these plants no longer contains any aspect of rebirth and is heavily burdened with violence.

Hyacinth : https://en.wikipedia.org/wiki/Hyacinth_(mythology)
Given that early-flowering plants are a very intuitive symbol of rebirth and the victory of life over death, can today's known Greek mythology be considered authentic and unchanged ?
