This does not quite fit your parameters for help. My request would be to give me types of plants/shrubs that I might use. I am replanting a portion of our garden and I could send you pics of the area that I am working on. Please let me know.
As you give no indication of the garden location, orientation, soil type or amount of sunlight, I am including a couple of links so you can choose the one best suited to your situation and work from there, see below.
If you are still unsure of how to go about creating the garden you envision, I would recommend you consult a landscape designer or experienced gardener in your area. If you have a local nursery or large garden centre, you should ask their advice and if they can’t help you, reaching out to Landscape Ontario would be a great starting point to finding a garden professional, link included below.
Hope this helps.
