Your scale is way off. You need something larger and taller. How about a large pot water feature set on a river stones.

Can we see a wider view of the whole area from several angles?

We don't need a wider picture.

You've got foundation, brick, fake stone, 2 kinds of vinyl siding, concrete pavers, and a drainpipe. No water feature in the world will fix the hot mess surrounding that corner. You need plants--one big-ish one and a few smaller. Go to a nursery and give them the important details. And get your County Extension office to test a soil sample. If it's acidic, go with it...rhododendrons and azaleas.

Is there enough sun to plant annuals?

I'd plant an evergreen shrub that grows at least 4' high x 3' wide and call it a day. One that likes wet feet - inkberry (if works for your area).

Nothing belongs that close to the foundation. A proper planting would start with some azaleas or such as tatts mentioned, my spade would START outside of your ring, or closest where the fountain is. Only landscaping (not mulch! Especially not dyed mulch) will beautify this area. More tchotchkes will just look cluttered

I would appreciate a wider picture as well. Landscape design has to look at the larger picture, not just a single small bed. I agree that the bed most likely needs to be larger, but how large and what shape will depend on what is not visible in the photo such as location of walkways, windows, and doors as well as other garden spaces so that they all relate and work well together..

The drainpipe absolutely needs an extension to allow rainwater to be disbursed well away from the house. I can see this bed could be a pool of standing, stagnant water, which most plants don’t like. Plus it’s never a good idea to have standing water at your house foundation.

Can you see this from the front of the house? If not, I would put a rain barrel under the downspout, and use the water you collect for watering other plants. You could and plant lower evergreens around it. ]

Really sorry, because I know how much work that water feature was, but it needs to go. Some laurels will grow nicely in the shade, as will hostas. Fix the drainage and amend your soil with lots of organic matter. Not scrape it into the top, but double dig it. Remove a foot of soil. Then dig down another foot and add lots of compost, composted manure or peat. This is where your extension agent can help with local soil conditions.

The wider picture always helps, but it looks to me like you're trying to put too much (and the wrong things) in the space. A single large shrub that works with the house, or a patch of groundcover or perennials, but not so many different small things.

If the soil is full of roots then you may be better off planting in pots.
