They should be fine in pots for a few weeks, until you can replant in late September, or even early October, but I wouldn't leave them in pots over the winter. Some will live, but some may die.

do what you have to do ...

AND DONT WORRY ABOUT HOW POORLY THEY LOOK ...

its a good time of year for such.. as long as you dont presume they will look pretty for the rest of the year ...

its all about the roots.. and the buds for next year.. not this years leaves... maintain such.. and you will be all set ....

I am in a warmer zone than you, but what I do is place the pots next to an east facing building, then pile lots of leaves or straw around and over them after the first freeze. They stay right there until spring. I have never lost a plant this way.

Thanks for the reassurance. I do plan to get them back into the ground before the first freeze. I have a bunch of new stuff showing up mid-late September to fill in my new wall terraces so they'll go back in with those.

You could always pot them up and sink the pots into the temporary holding bed. That way if you get to replant great! If you don't, then they are ok in the pot/ground, just be sure to mulch over winter. Then replant in the spring.
