You are right, this isn't Viburnum opulus. The opulus leaves look like...duck feet? I think it is the Leather Leaf Viburnum; Viburnum rhytidophyllum. The tomentoseness (is that a word)? rather the fuzziness of undersides of leaves, stems as well as flower stalks are pretty definitive for this species. Grand plant.
Yours however, I hope were on sale. I'd get these guys transplanted in fresh potting soil like now and check the roots for browning and rot. Check with the nursery on last date of fertilizer as well as formulation. These are large evergreen shrubs, great for a park like setting, privacy. You need to get them healthy before planting in the landscape. Zone 8a, right? Yup, evergreen all year round.
This plant is a coarse texture. Coarse textures on the periphery make for a smaller seeming space. Fine textures, enlarge a space. Depends on what you want to do. Coarse textures, large patterns that you can see from a distance trick your mind into thinking they are closer than they really are. Fine textures such as your Lespo shrub, since you are unable to see the detail clearly, recede into the background causing a more expansive feeling to the scene. Same with fencing if you ever do any on your property in the future. Grapestake fences, fences with fine texture, dove gray will recede. Board and Baton fences with obvious texture easily seen from a distance will come forward making a space...more intimate. For colors, black recedes and white comes forward. Gray belongs in the landscape where a purple wall will stand out as a focal point. Sorry, I know this sounds off the beaten track but for you and your landscape, I think you are at the point where having more information will help you choose plants and have better ideas of what you want to create.
Leather Leaf Viburnum
Edit: There is a good chance you will not be able to ID this plant's genetics by its phenotype. Lots of hybrids are grown as Leatherleaf Viburnum needs a partner, it is not self pollinating. This could be Leatherleaf X Opulus, or Leatherleaf X Mariesii. This article I posted talks about that very thing being a problem with ID. The proper name for your plant (without a DNA test) would be Viburnum X rhytidophylloides not V. rhytidophyllum. The latter they want to reserve for the full blooded (grins) Leatherleaf Viburnum. This is the best I am able to do based on a picture. Still waiting for better ID's myself. See, I was always able to SEE the actual plant, I actually taught plant ID three semesters taking my class out of doors for lab. They had to ID for tests via a branch or bud in class and I'd take them to different plants different locations on campus they'd not seen during lab I rarely did any work with plants by pictures. Seeing, touching, feeling is very different than a flat 2D picture. I did better IDing by looking through microscopes at previously frozen flowers and using a book 2" thick of a dichotomous key. Ugh. I am practicing IDing via pictures. Always nice to have wrong answers to help support the right answer? But so far, I haven't seen a better one.
This is what your plants should look like coming from the nursery. The baby plant in the picture is not suffering from cold and as it matures the leaves become heavier and do the hanging down thing. It will not look like this as a mature shrub.
