Looks like littleleaf cotoneaster, Cotoneaster microphyllus. It is fully evergreen in my climate and I have never encountered any issues with lacebugs. It can sometimes be prone to cotoneaster webworm but even that is rather uncommon here.

This looks to be one more on the order of the deciduous Series Horizontales cotoneasters to me, one that I do not recognize - a body has to be careful about firing off cotoneaster species names as there are hundreds of them, with multiple different kinds having long been grown under the wrong designations in western gardens for many years. For example, plants labeled the aforementioned C. microphyllus are often instead C. integrifolius.

Growth does not look as jagged/angular as most of the horizontalis types display (albeit I will readily admit that I have not seen them all). And it also very true that the specific names are often confused with this genus. But it won't be long before you determine if this is evergreen or not......

Horizontales, not C. horizontalis - as in CC. divaricatus, ascendens, atrovirens, flinckii, hjelmqvistii, spongbergii, atropurpureus, horizontalis and perpusillus. Not that this example necessarily belongs to this Series at all - there are 37 of them.

Thank you. I read what you wrote. Please note I said horizontalis "types" as that is what that grouping of cotoneasters is named after. And FWIW, very few of the those species are widely available in commerce.

Is it really necessary to be so pedantic in your responses?

We are talking about a botanical Series that includes plants that do not necessarily look exactly like C. horizontalis. And includes other species that have a horticultural presence. The plant in question is clearly one of these (or a member of another Series with generally similar leaves and branching) and not one like C. integrifolius.

I just heard back from the person who planted it, she says it is 'Tom Thumb' and it is deciduous. This plant at least has no history of lacebug.

I recognize that rock garden LOL. Green Springs Garden, right? They used to have some rare South African geophytes in there like montane species of Cyrtanthus. I wonder if they died off in the cold winters.

Right you are davidrt28. GSG is a great resource for Fairfax County.
