It should be ok, like any other spring blooming bulb they need the cold winter to bloom properly but if the temperature drops below 50ยฐF (10ยฐC) Iโd recommend bring it indoors
Spring crocuses are hardy plants that can tolerate cold temperatures. However, if the weather in your area is consistently below freezing, it is best to bring your crocus indoors to protect it from frost damage. You can bring it back outdoors once the temperatures warm up again.
