I really have not gotten into native grasses, but here is a good article on it from Pennsylvania.

Also, here an overview of warm season native grasses on the GNPS website with some resources listed at the bottom.

OK, then any lower growing shrubs? Not the other evergreen blueberry, please. I will use that elsewhere. I'm looking for something without dusty grey or blue foliage because these plants will be layered together....
I also need an evergreen groundcover that can take chunks of clay mixed with compost. It's not a very pretty mix of soil in that area, but I've done my best. It's red clay mixed with Kaolin clay and county compost.....

In regards to groundcovers, both Green N Gold (Chrysogonum virginianum) and Mouse eared Coreopsis (Coreopsis auriculata 'Nana') are tough and at least semi-evergreen if not fully. Last year, both were available in Home Depot as quart/pint perennials.

For low growing shrub, look into Rhus aromatica 'Gro-Low' , but it is not evergreen.

Rhus aromatica 'Gro-Low' would be fantastical but way too large. I think I'll use it on slopes though! I love it!!

I already have the two others you mentioned.... (not trying to be hard on 'ya esh....it's just I want something new and different than I have in this spot!!).

Hey, I am not offended - I'm glad to hear you already have those.

Given that you have morning sun but afternoon shade, here are some other groundcover suggestions.

Esh, I just don't wanna be too hard on your brain!! I have ordered a few more native plant books. I have the Foote book but I find it difficult because it lists just about everything, garden "worthy" (for a city garden, that is) or not.
I like the idea of the lyrata sage. I have it in quite a few places, and I don't have purple in this area anywhere and could sure use it. Plus, this is care free as it multiplies on it's own!
That is a good article.

I would like to grow pussytoes. I've tried a few of the other things listed in this good article, and they did not sruvive for me....galax, pussytoes, partridgeberry - what do they really like? I thought I had found great places for them, but I guess not.

I think the article describes what they like. I have pussytoes naturally - an especially happy patch along a path behind the house, nothing special. Galax is often found on a slope, but I have transplanted it to other places and it is happy there too. Patridgeberry seems like it a little moist. The thing about native plants, you can't be too nice to them or you'll kill them with kindness!

A great book on native grasses (and ferns and mosses) is the relatively new one by Cullina.

I have sea oats and enjoy them. But..... Perennial
