I'm still learning exactly what is native... although I did have other plants in bloom it is possible that they are also exotics and less appealing to the pollinators.
My mother-in-law kept dropping off random plants on my doorstep when we moved in this Summer. The ones I can remember that were planted in the back with the RoS are cone flowers, catmint, forget-me-not, and mazus reptans. She also gave me a gorgeous orange bloomer and a red bloomer that were very popular with the hummingbirds, but I can't remember their names
The plants that were already established out back are dianthus, phlox, coreopsis, lilly of the valley, fern leaf bleeding heart, evening primrose (identified by you!), another variety of primrose, obedient plant (also identified by you), daylillies, purple Siberian iris, shasta daisies, wild geraniums, cleome, cone flowers, lots of black eyed susans, new england asters, and mums. There are a few smaller plants that I either haven't identified or I can't remember them at the moment. Besides the black eyed susans, I'm not sure what else is considered to be native....?
Thanks to some of your suggestions in other threads, I'm hoping to plant some bee balm, butterfly weed, and cardinal flowers next season.
Just how noxious is the euonymus? It doesn't seem to creep like the vinca and put out roots. Does it just get massive quickly? Is it something I can trim up to keep it under control? I wouldn't mind replacing it with some confetti abelia, which has a somewhat similar look but is attractive to pollinators. I adore the little one I planted in my front garden! However, I have lots of plans for creating new gardens in the front (you may remember that thread) and my budget may go towards establishing those. I'm constantly trying to store away the things I learn from you so that when I establish my new gardens from scratch they'll have some good strong natives in there
