Can Houseplants Affect Human Intelligence?

Owning a houseplant can increase your attention span. This is because humans have a limited capacity to focus, and looking at a houseplant, or simply nature in general, appears to help rejuvenate that capacity. Though just how houseplants affect intelligence is still debated, it's clear that having one around can improve your thinking process.
