Hmmmm, certainly is one of those two! Curiously, I actually HAVE a Stylophorum diphyllum which I got at a plant swap a year or two ago. But I planted it on the other side of the yard, in a wooded glen (I am going out right now to compare the two!) Is there a definitive way to tell the two apart at this stage of growth (before they've bloomed but while they are in bud)? I'm guessing it's far more likely I've got a boatload of the non-native (and undoubtedly invasive?) Chelidonium majus, but wouldn't it be wonderful if that boatload was of the natives instead!

There are lots of white flowering things, but color - lasting color - is harder to come by. I'd look into Green and Gold (Chrysogonum virginianum) and Mouse eared coreopsis (Coreopsis 'Nana) first. By the way, my Home Depot north of Atlanta is stocking both of these as pint sized perennials right now. There is also Iris cristata (tiny iris, so cute!), Monkshood (Aconitum species), Phlox divaricata (cultivars often available), Campanula divaricata (bellflower), Bellworts (Uvularia), solomon seals (true and false). Hope that gets you started.

I know that for many of you, the white centers grow beautifully. So do the white margins. However, those are the ones I have the most difficulty growing. Every now and then an exception, for a couple of weeks maybe, then downhill from there. So I got Patriot and Minuteman before I knew they would not do much here. I got Ann Kulpa. I got White Elephant and Eskimo Pie. Surprisingly, White Elephant (a 2011 purchase) does fine before it turns green about mid June. I lost my 2010 purchase Eskimo Pie, it dwindled to nothing, and I consoled myself with Hudson Bay. It is doing nicely. So are Pathfinder and its offspring Half & Half. Where I find solace is with the golds, and the greens--which includes all the blues which turn to green. When blue wax does not WASH off, but melts instead, the leaves wind up glossy and fairly smooth. You'd have a hard time identifying some of mine which you'd recognize if they were blue and matte finished.

I think you need something a bit bulkier. A multi light pendant might be pretty. https://www.potterybarn.com/products/clift-seeded-glass-3-light-cluster-pendant/?catalogId=84&sku=2154081&cm_ven=PLA&cm_cat=Google&cm_pla=Lighting%20%3E%20Pendants&kwid=productads-adid^202405455838-device^c-plaid^295396197027-sku^2154081-adType^PLA&gclid=CjwKCAiA_c7UBRAjEiwApCZi8eDhOL9ULmRxHn2JhU0vQC2k9_PABRJq1jjzE5puywsZT9UuJO-0AhoChJwQAvD_BwE&cm_ite=[[PLA]%20-%20Good%20Desktop] As for barstools, something like this that provides some contrast against your island would be nice. https://www.jossandmain.com/furniture/pdp/east-village-24-nail-bar-stool-lopk3029.html
