I have a 12 foot high wall next to my patio. How can I quaint-ify it?

In my backyard, adjacent to my patio is a 12 foot high wall that is brick painted white. It’s a wall of my attached garage and adjacent to the wall is a 4 foot wide planting bed. On the other wide of the bed, adjacent to the bed and opposing the wall, is one side of my patio. My question is: How can I dress up the wall to make it something appealing to look at—something that goes with the rest of the garden, which has a rustic English garden vibe. The stark white wall is a currently empty—no vines or ornaments or lattices—so it’s a bold focal point. I’d like to soften its appearance, maybe green it up with some vines and possibly lattices, but maybe also some simple ornamentations, artifacts, etc. Anyone have suggestions? I thought of sandblasting the wall to reveal the brick but that sounds like a big job. Maybe paint it a muted green/grey/brown color to sort of blend in to the garden color? Or should I go a bolder, more interesting color to make it pop? What can I do to make the wall look like it belongs in a quaint English garden? Make it more interesting?
