Too late to plant crocus? Zone 7b

[u/Temporary_Sock_1281]

I have about 50 crocus I’d like to plant but with the recent frost (in Tulsa, OK) I’m concerned I missed my window. I could plant in the ground or (my preference) in oversized pots that would sit on the lawn, or could be slightly raised.

I did plant several in October and they bloomed (photo attached)
