I am moving and still have butterfly weed in bloom. I have successfully repotted about 100 new plants that came up in my yard. I have 4 pots full on plants about 4 inches tall. Should I leave them in the pots and let them freeze back there or plant them in the new spot in Seven Points, Tx? I'm afraid they will die if I do that. Does anyone think I'll be successful in this endeavor?
