As the daffodils slowly faded away their skin became transparent, their color faded and the flower wrinkled in on themselves, but it took me days to throw them out. I wish I has allowed them to form their seed heads, something I never allow them to do in the garden as it takes energy away from the bulb and next years flower. In the garden I'm ruthless. Flowers fade and it's snip and into the compost. I have never tried to grow daffs from seed, I have always planted bulbs. Wonder if it would work or if the bulbs have been sterilized?
