Not at clematis are the same, but our Jackmanii don't even wilt when torn apart like that.... tough as nails. Can help to give them some shade for a few days (~3 to 7 days?) while they adjust.

What Bostedo said and yes, they will more than likely survive. It might help if you cut them back a bit, or cut the leaves that are left in half, especially the morning glory, since there's not the same volume of roots to support the top growth.

Thank you, I think so far only a few leaves have died, and growth was stunted a bit, but overall not as bad as I thought it would be! Lesson learned, get big pots from the start, no matter how small the plants are at the moment!
