Green Idea for garden wall.

Don't know what the plant is called but available just about everywhere.

Easy to grow, just break a bit off and stick it in the ground. Likes shady spot and lots of water to get started.

Hold the shoots on the wall with cable clips and water the wall till the roots take hold on the cement blocks.

Makes the area look and feel cool. Good for a quiet corner in your garden or round a BBQ patio.
