Vertical Garden in the Process

Virtually it would have been an impossible task as to put each individual plants together.
To identify the best selection of what can or cannot handle this order of things.
Few plants had failed in the process.
I find that these plants cannot handle the stress:

1) Spiderplant - started to root rot and leaves falling away.
2) Madagascar Periwinkle - became leggy and failed to bloom
3) Annuals & Flowering plants.

I guess its all trials and errors.
Somehow the best that makes the difference are the coloured ones.
These foliage seemed to be happy receiving limited bright shaded light.

Another plus point is having a free open space on ground.
That way - watering is actually considered economical & effective.
