I wish to place some plants to block outside of my shop as the door is facing the staircase. But what type of plants should I put and which position should I place it?

1. Since the door is facing the staircase, the concept is "if it is not seen it is no longer a threat" applies. Thus, it should be placed such that the staircase is fully or partially blocked.

2. In Singapore weather, the most common - easy to maintain are those from the bamboo family is one of the easiest to upkeep. The yellow bamboo and common straight growing ones are OK. Any other plants so long as they don't have a single trunk would be accepable.
