Multi-level/exposure country dilemma
I love reading through these forums for your "expert" advice. I always enjoyed gardening, but have so much more to learn! Thank you in advance for reading my lengthy post, and for your time and suggestions.
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.
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!
