Here you have a guide of hexagons which can be formed in any shape you like. With the clips you can click the hexagons to eachother.
The standoffs are standard 25 mm of the wall. You screw the standoffs with one screw on the place you like and when the hexagon is put in place you won't see a screw anymore.
Since there is space between the wall and the hexagon, the plant can curl behind the hexagon which makes a nice guide for the plant.
Tips:
Clips - For a tight, but really tight, fit you have to print the clips at 100% scale, for a bit more lose fit, but easier set up you would like to print the clips on 95% scale.
