Are they the same thing? Different variety? Can I just gather some in spring and have the allegedly most expensive spice in the world for free?
YOU CAN ABSOLUTELY GROW SAFFRON CROCUS BUT THAT PIC ON THE BOTTOM IS NOT SAFFRON CROCUS.
I grow saffron crocus in pots on my patio. It’s hardy to zone 6…mayyybe zone 5 with protection. Colder than that, and you have to move the pots into an unheated garage or root cellar to ride out the cold.
But saffron crocus are unusual in that they bloom in FALL! Around here, mid-late September. The crocus you see in spring are a different variety and not edible.
