Answer: I would include small azaleas, alpine rhododendrons (such as Ramapo or Purple Gem, maybe heath or heather, pieris, sky rocket junipers or perhaps even dwarf conifers. Depending upon whether you have shade or sun you can fill in around the shrubs with perennials or annuals for color splash. As you are looking through the garden center be sure to choose either sun loving or shade loving plants depending upon the sun or shade exposure in your planting beds.
Organic mulches such as shredded bark or bark nuggets or even cedar mulch are good walkable materials for walkways, or you can use stones or gravel.
Best wishes with your landscape!
