Next to a walkway I plant white alyssum so it will spill over the bricks, softening the edge and reminding me of a lacy white petticoat peeking from beneath the schoolmarm's serious black dress.
I also use clematis vines to scamper over the walls of garden rooms, and shade-loving golden lamium to light up the borders and edging along my woodland path.
But you can use a lot more than plant material to soften the hard lines of your garden's foundation. I love to cruise the tile selection of my local Lowe's store, collecting interesting tiles to dress up my patios, walkways and most important of all -- to bedazzle and accent my new brick wall.
I've found that tile will adhere to just about any outdoor surface if you use the right adhesive. Locktite PL Premium Construction Adhesive is what I use to secure colorful tiles to boring fence posts, affix flowerpots and glass balls to the top of my blue bench, and especially to glue my favorite tiles to the niches in my brick wall.
When using construction adhesive I make a brace or support to hold the tile in place overnight. Then before winter arrives I caulk all around the edge of the tile with clear caulking to keep out the rain. Just to be sure my favorite tiles won't crack, I also give them a spray with an outdoor sealant.
