The Weigela might not have enought sun to flower well, and a Pieris, unless you get one of the few dwarf ones, will certainly get too big. It will also require acid soil. And if you have acid soil (and don't have deer), an azalea or small rhododendron would also work very well. Rare Find Nursery has awesome selections.

Our property is about 15 miles north of Greenville- only a few miles from the mountains, so I imagine it is a couple degrees cooler than Greenville. Elevation is about 1100'. According to GIS info, it is sandy loam. It looks like red clay to me, although fairly loose and gritty. There are a few wild mountain laurels on the property(I think). It is mostly oaks and hickory. I assume it is somewhat acid, since there are several luxuriant patches of moss. Our 7 acres is basically the north slope of a hill, from top to bottom. It seems damp at the bottom of the hill, although I saw no evidence of water. I don't think there's any walnut, but I haven't looked at every single tree. I'm particularly fond of rhodies- any variety, so long as they do well w/o a lot of work. Do deer eat rhodies? I'd like to add to the landscape without changing it too much- plants that are shade tolerant and look like they belong- natives, in other words.

Thanks for letting us know! I never thought of trimming evergreen wisteria like that. There is a huge one flourishing at the Fort Worth Botanic Garden, right behind the conservatory so they may actually be marginally hardy here.

Thanks, the input is much appreciated. I'm still new to gardening (starting my 4th year), but for 30 yrs I did analytical chemistry in a food testing lab. Early on I got tasked with identifying off-odors due to spoilage or contamination. In my spare time I pursued pleasant odors too, and examined the composition of many plants, beverages, flowers, essential oils, etc by mass spec. So I got some solid objective data on what's present in the scents. Nevertheless it's not a magic wand that can "test for everything", and of course human sensory perception will vary wildly. Most grapes don't have a strong smell, except for the Concords. Regular Concord grapes (the ones with seeds, rarely available in grocery stores here) have methyl anthranilate predominating. There is some ethyl anthranilate in Texas Mountain Laurel (I never thought TML smelled like grapes; the mild pleasant smell comes from ethyl benzoate, IMO). This shrub had more aminoacetophenone. Corn tortillas have a faint hint of aminoacetophenone. Admittedly the food/snack industry overuses synthetic grape scent to the point it gets sickeningly sweet. Welch's purple grape juice is a halfway decent substitute when the fresh grapes are out of season. I just started my seasonal check on this shrub, and found it was removed recently. It had been next to the sidewalk of a post office near my old workplace. My yard is small and I wasn't able to grow one anyway. But thankfully before retiring I did get chemical analysis on it 2 years in a row to confirm/refine my (subjective) olfactory diagnosis. I'll stop now without commenting on cat urine odor!
