I lack creativity in design and can get fixated on one plant or type of plant but I’ll offer suggestion anyway, what about simple a row of ornamental grasses? Morning light miscanthus I think could be nice. It looks like there’s an ornamental grass up the driveway close to the privacy trees. If it is, maybe you can just divide that and use it. It kind of looks like the one you have is miscanthus but if picture was taken today I would think it would have more growth. Id remove all the plants, replant the ones you like elsewhere if you want, and edge the bed if it needs it. As for weeds, try a roll of construction paper from Home Depot, roll out 2 layers worth under the mulch. Wet it all down after. Just my 2 cents. Also, if you did the grasses or some single row planting, you could plant perennials in between them, something that hangs over the brick wall. Can’t think of any good ones off top of my head.

Here’s a ChatGPT image

Do you have an emotional need to grow ornamental plants there or would you prefer to fill that space with lawn?

Northwind switch grass, I don’t think it’d be end of world with miscanthus but here’s another look. There’s other switch grasses you’re probably much more likely to find at local nursery like heavy metal

Mulch to keep the weeds down, and add more plants, or rearrange the plants you already have. The plants you have seem to be scattered out randomly, with no pattern or organization.

@woodrose yes it definitely feels like plants were just kind of plopped where ever without rhyme or reason. Can I move them now or do I need to wait for Fall?

@cecily 7a I definitely don't have any emotional attatchement to anything specific here. It's also deceveingly wide so maybe I should make it more narrow
