I've made a start.... thanks to Julie, Rick, and Leaves. It's almost tougher when you have a list of varieties then when you go 'looking' without knowing exactly what you want. And, of course, it's still early so nurseries are just starting to get the shrubs in. So far, I've found: Amelanchier alnifolia 'Regent'(Serviceberry/Juneberry) and Aronia melanocarpa elata (Glossy Black Chokeberry)- Both found at Sargent's on 2nd (Rochester. Viburnum 'Blue Muffin' found at Owatonna's newest nursery Turtle Creek. And, just today Viburnum 'Onondaga' found at Nagle's Sod and Nursery on I-35 south of Medford. I have to say, I love Onondaga! The spring color is just lovely. I have planted it near a deep evergreen tree on one side and with the silvery Chokeberry on the other side. That little section should just be stunning when the shrubs get a little growth on them. I think the golden current and the 'Kelsey' dogwood might be the toughest to track down. I've found plenty of 'Alpine' currents but not the golden variety. Same for other varieties of red twigged dogwood but I'm kind of stuck on Kelsey for it's small size (2-3' H&T). I can always mail-order, but would rather do business locally if I can. BTW, for anyone who hasn't been there, Nagles has the greatest selection of iron (the natural rusty looking variety) garden accessories. I ended up buying a bench and trellis's as well as the viburnum. They also have a lot of concrete yard art, benches, etc, but it was really the iron that got to me!

Other than a susceptibility to Verticillium wilt (as are many other plants), not much bothers the doublefile. Without a doubt one of the most striking shrubs when in flower! Normally I would not suggest to prune to control width - that very wide, layered branching is one of their premier attributes. But the cultivar 'Summer Snowflake' tends to have a very upright, less spreading habit and can be much more easily kept to a narrower width. Also blooms sporadically throughout summer rather than in one big blast like more traditional cultivars.

There are quite a few viburnums native to North America and the United States, and many more that are not. Some of the exotic species and hybrids are quite tame, and others are not. Viburnum nudum is native to North America, basically in the southeastern United States. The pictured plant is Viburnum sieboldii as noted by @arbordave (SE MI). I have observed seedlings sprouting around Viburnum Valley from parent plants I've grown over the past three decades, but I'm not aware of true invasiveness elsewhere. Easy way to separate this plant from most other viburnums: crush and smell a leaf. Unmistakeable fragrance of green bell peppers!

Partially consumed leaves on a deciduous tree or shrub at the end of November is not an issue for concern. The plant is entering dormancy and the remaining leaves - or parts of them - will drop off in a week or two. But it is something to keep an eye on next season. It is also very likely the katydid you saw was responsible for the leaf damage. Depending on your location, maintaining a containerized shrub outside over winter can be risky but it is equally risky to hold one over indoors. Garden shrubs are not houseplants :-) You can keep somewhere that stays cold but doesn't freeze (a shed, unheated garage, etc.) but the safest method is to dig a hole and sink the pot into the ground. The surrounding soil mass will insulate it until it is time to replant.
