Only if it's the saffron crocus (Crocus sativus), which you'll be able to tell by the saffron colored stigmas... Unlike most spring growing crocii this ones an Autumn flowering varietal...
I have managed to save saffron from the autumn flowering Crocus Sativus- I just dried it out on kitchen paper. Unfortunately there was no sign of the plants the following year-possibly a tasty treat for mice?
