I posit that the photo above DOES show extended wings, though without further information I absolutely agree that it doesn't have the widest/biggest wings of a Euonymus alatus individual that I've ever seen. There used to be one sold as 'Monstrosus' from Chicago area nurseries that could be used as a glider. Here is an image from the Morton Arboretum's herbarium collection that looks similar to the photo above: http://redwood.mortonarb.org/images/jpg/sheet/4/0035464MOR.jpg The posted photo above appears to almost taken in "plan view", i.e., directly from above and doesn't provide nearly the information that photos from various other angles might provide. "Wings" on 'Compactus' are often/always reduced to lines on the twigs - nearly absent. I believe what I see in the photo above does not equate whatsoever with "nearly absent." I'd say they equate with "average winginess" for the species. I also think the photo angle may create an idea of denser twigginess, but examination of the number of bud breaks along the stem for additional twigs along those main branches shows that there are fewer (far fewer) than one will see on run-of-the-mill 'Compactus' in eastern US landscapes. I did not suggest that "...the plants make different wings in different parts of the country..." I suggested that when a plant is typically found in abundance in a certain region - and some participants here may have encountered it far more often than other participants - that the seeker of information consider that when assessing the posted information. I would assert that your evaluation of plants and performance for northwest coastal conditions is superior to many contributors here. I do believe that plants can express different growth characteristics in different locations (not necessarily winginess of twigs, but certainly things length of shoots during growth spurts) due to common variables like fertility, moisture levels, daylength, etc. Certainly traits like maximum size for a species will be different in the Ohio River valley region than in the Puget Sound region.

Viburnum. Perhaps V opulus but I don't know what species might occur in your area.

Looks like an Indian Rosewood. EXTREMELY invasive, sends up root shoots up to 60 feet away from the tree, and has roots that will completely destroy the foundation of your home. Take it out NOW! There were two in the yard next to me at my old house, and I had shoots coming up on the other side of my house from roots that had grown under my foundation. When those roots start to get larger, they can crack your foundation. Seriously, get rid of it!

Cornus subg. Thelycrania of which this planting would be an example if it consists of a dogwood species does not strictly adhere to opposite leaf arrangement: Cornus in Flora of North America @ efloras.org I'm not sure it makes a huge difference whether Kay 21 thinks the planting is in USDA 5 or 6, with the geographic location of Utah at 6100' probably being the most important combination of involved circumstances.
