Perhaps V. x rhytidophylloides. It having been moved at this time of the year and in this condition - still actively growing - expect wilting and perhaps shriveling, even failure.

Anyone have any more info so I can read up on how to best care for it?

==>> i would think that general care rules for V is good enough.. cultivars rarely differ from the norm.. unless the leaves are variegated with a lot of white .. and then you would favor a site trying to avoid direct sun in the heat of the day... but i digress ..

if the root mass was as large as the plant you see above ... well.. you cut most of it off ... as such.. you are responsible for water ....perhaps all winter, since you dont mention where you are ... and because its large.. all next summer ... and then the following year probably only in drought ...

i would suggest you planted it too close to the house ... but i can intuit why .. a little privacy on the porch ... due to such.. you will be heavily pruning it when it gets re-established ... and i suggest you do that without just giving it a haircut once or twice a year ...

it is very stressed .. water properly for 2 years.. it will NEVER be hungry... just skip fert .. and never fert a stressed plant ... and it will technically be stressed until re-established ...

see link for watering .. it all depends on your soil.. and how water moves thru it ... water deeply .. slowly.. thru the rootball planted .. and then let near dry before another deep drink ... insert finger and find out ...

it will NEVER be hungry

You have no way of predicting this.

Click on Establishment of Container Grown Plants in column on right. Basic information is still pertinent even though the shrub asked about was not growing in a container at this time.

Ken- we are in north Alabama. I read how to take a hardwood cutting to root a new plant... it's too late in the season to get a softwood cutting. I'm hoping either way I can "save" it. These are supposed to be evergreen in my area, or so I've read.

Cutting is too long. Otherwise at this time of year it probably corresponds to semi-hardwood.

So would I just leave the top leaves or no leaves?

If you are going to use the simple 'stick it in a slit in the ground and forget it for a year' cuttings technique the length is OK. Half will be in the soil. But if you are doing a more controlled pot method it's too long.

Not sure a kind with large persistent leaves such as this is suitable for being stuck in the ground and left in the open all winter.

It would be OK in my climate, not sure about the OP's region. It would probably drop its leaves but would bud out in the spring,
