Background:
We purchased our home three years ago. It sits on a few acres in a rural residential area. The previous owners idea of landscaping was a run-down haphazard mess. It's been a major work in progress, but we've accomplished a lot. Because of the time and money we've invested, I try to research a lot BEFORE sticking a new plant in the ground. But, I really need some advice.

My dilemma:
As you will see from the pictures, we have a foundation flower bed that extends from the front of the house under our wraparound porch, around to the side and the extends outward as it undulates down a hill with a couple of landscape walls and finally tapers off on the back of our home.

The front of our home has southern exposure, which means it gets a lot of hot sun, all day long in the summer. The side of the house is eastern exposure. It too gets a lot of sun, but it's early in the day. The back of our home faces north. Aside from some morning sun slanting from the east, it's shaded all day long. I am trying to plant a flowerbed with shrubs and perennials that look cohesive despite the variations in exposure and levels. Review the pics below to see what I mean.

Here is a photo of the front, southeast corner of our home and flowerbed. I currently have lavender near the front porch steps. I then staggered green gem boxwood and dark pink double knockout roses. I have silvermound planted in front of those.

East section of the flowerbed, top level. Here, I don't have much. Not sure how to continue the foundation landscaping. I don't necessarily need to cover the stonework. All I have thus far is a yellow coreopsis, three sedum, a couple of redhead perennial grasses that grow on top of the wall (they frame the view to our backyard nicely, I think), and a few pink coneflowers.

East section, bottom level. Here I planted a Sandra Bernhard peony against the wall. I also have a couple of Wine and Roses weigelia on either end of this section.

Rear view of side, north section (Gotta love yellow siding. Power-washing is on our to-do list this spring!) I only have a couple of yellow and pink coneflowers I stuck in the ground beneath the wall after moving them from elsewhere. Not a good spot for them, since it's so shady.

Thoughts? Again, I am looking for a nice mix of shrubs and perennials. I am willing to move my existing plants as needed. My garden also needs to be deer-resistant. I already have daylilies and roses in the front that I must spray to repel the deer, so I don't want to add any more to the mix. I also don't want anything invasive!

I am currently considering the following plants, but am not sure of the layout, or how they would look with my existing plants:
1) Perennial geraniums, Rozanne and Kashmir White
2) White and pink coreopsis, if I can find it.
3) Hydrangeas? Annabelle, Blushing Bride or Invincible Spirit
4) Siberian Iris I have growing elsewhere on my property that need to be divided and moved
5) Creeping phlox? Sublata for a sunny area or the other kind (?) that is shade tolerant

Thanks so much!

Here is a link to a photo of the front our home, so you get a sense of the big picture.

Here is my attempt at an embedded version the same pic, but this time the URL is from a different photo-hosting website.

Here is a "big picture" view of our home and property.

Here is the front, southeast corner of our home. Notice how I have double knockout roses, green gem boxwood and silvermound repeated in the front. I also have a lavender plant on either side of the front step. Love the scent, but not sure it was the best choice.

This is the upper, east-facing section of our landscape bed. I have three sedum, a yellow coreopsis and a couple of pink coneflowers left over from plantings that were elsewhere around my home. I also planted a couple of redhead perennial grasses on top of the wall. When mature in summer, the grass frames the view to our backyard quite nicely.

Here is the lower, east-facing portion of the bed. I have a pink Sarah Bernhardt(?) peony against the wall. The bush under the window is a wine and roses weigelia. It was there when we purchased the home, and I'm hesitant to move it because it's very established and blooms well. However, I will move/dig it up if for the greater good. Last summer, I also planted Morning Light maiden grass in front of the pipe that goes up the side of our house, but not directly in front of it, since the meter guy needs to get back there :)

Here is a view of the lower, north end of the bed. You can also see the newer, small, Wine and Roses weigelia I threw in last summer. I'm not convinced it's a good spot for it. As for under the wall, all I have are a couple of poorly placed coneflowers. I'm sure it's too shady for them most of the time. Also, at the left (east end) of both walls, I have a dwarf perennial grass planted.

As you can (hopefully) see, I'm struggling between the more formal look of the roses and boxwood out front, a sort of prairie-style side, and ??? in the shaded end. How the heck do I make it all work? Also, I really like the roses out front, and my peony by the wall.

Also, do you have any recommendations for the side, by my stonye foundation, and on the lower level near the weigelia and peony? I can post another pic with a more complete view of the side of the house.

Your thread didn't offer a good square on shot of the side of house. However, it looks like one thing you need is some groundcover to link the disparate plants. If you put a good picture up, I'd take a look at the shrubs.

One planting scheme that is guaranteed to look unsophisticated is alternating, disparate shrubs. While "cute," nothing says amateurish quite like that does. I'd reconfigure near the front steps. Here are plant suggestions... or re-use what you have in a better way, or some of those new things you're after. The silver mound would work as a groundcover if there were a lot more of it.

Here are a few more pics that may be helpful.

Front. This shows the boxwood, double knockout roses, silver mound, and lavender near the steps. I really like the roses because they bloom all summer, so would like to leave those in place if possible. You can also see that I have daylilies planted in the mulched area within my sidewalk. I could probably divide and add a few more of those around the house if necessary. Although, the deer like to munch on them, so I hate to use to many on the side or it will be like a buffet...

Here is a full side photo. Again, the top area currently has sedum, yellow coreopsis, and a couple of cone flowers I have two stands of Redhead fountain grass planted near the wall. Middle lower section, to the left near the wall, I have a peony plant. The shrub under the window is the Wine and Roses weigelia. The smaller shrub to the right is another WR weigelia. In the middle, to the right of the meter, is a stand of Morning Light maiden grass. I also have dwarf fountain grass planted at the ends of the walls, facing the camera. It may be worth noting that I do have perennial grass elsewhere on the property, so it somewhat ties in...

Last but not least, a broader view looking down the side of our home, so you can see the perspective.

Thanks so much!

Agh! This is why I go crazy. I do appreciate the suggestions.

At the front, I would try NOT to cover a lot of the foundation. As a groundcover, the Geranium would be too tall for my taste. I'd be looking for something that stayed below 6". I may not hit on just the right plant solution for you. I'm more trying to show you a layout. You can research more about the plants locally and online to find what is just right for you. Or someone else here may have a better suggestion.

You can add to them, too, over time and expand your bed, and you'll be able to see the roses better from inside the house.

And, of course I teach my child not to eat plants. I also realize there are many, many poisonous plants. But, there is something about Lily of the Valley. I remember being fascinated by it as a small child, due to it's miniature size and bell shape, exceptional scent, etc. So, I just don't care to have it around until I have older children. Just my preference, even if it seems odd.
