Plants aren't just good for the mind, they are proven to remove many of the nasties in the air which makes the work place a better place to be and can dramatically increase productivity. Psychologically flowers are also proven to have a positive impact on personnel by lifting their spirits and again encouraging better output. And that's why so many companies are realising that far from being a waste of money, the right flowers and plants in the working environment can actually pay for themselves time and time again.
