I am wondering why my saffron crocuses (or is it croci?) are not flowering again this autumn. This will be the third year they haven't flowered. They have multiplied and have lush green leaves but never any flowers. I had them in a raised bed which gets a fair amount of sun but a few weeks ago I lifted them up and put them elsewhere. Some are now in pots and tubs too but once again no flowers.....yet.

Any ideas out there would be most welcome.
