Flowers and plants in the office: what the evidence says

"Office plants increase productivity by 15%" is a line that gets repeated a lot, and it is worth a close look before you put it in a proposal.

What is documented

There is a body of environmental psychology research on the effect of greenery in workspaces. The most consistent findings:

• Lower perceived stress. This is the most replicated result. The presence of greenery is associated with lower self-reported stress.
• A better perception of the space. People rate the quality of their workplace higher, and that is linked to job satisfaction.
• Attention recovery. Attention restoration theory holds that looking at natural elements lets directed attention rest. There is reasonable evidence for this in tasks that require sustained concentration.
• Less perceived noise in large spaces with plenty of plants, through absorption and a psychological effect.

What needs qualifying

• The productivity figure. It comes from studies with small samples under specific conditions. The direction of the effect seems real; the exact percentage cannot be carried over to any office.
• Air purification. It is the most widespread myth, and it does not survive the move from the lab to a real room. We go into it in plants that purify the air.
• Plants do not fix a bad work environment. It sounds obvious, and it needs saying: if the problem is management, greenery does not touch it.

What to put where

Space	What works
Reception	A fresh weekly arrangement or a large plant. It is what visitors see as they walk in
Meeting room	A low, unscented arrangement: people talk there
Desks	A succulent, pothos or African violet. They take up little space
Shared spaces and kitchen	Large low-maintenance plants
Windowless hallways	ZZ plant or snake plant, rotated to a spot with light

The real problem: who takes care of them

This is what sinks 90% of office plant initiatives. Twenty pots get bought, whoever remembers waters them, within three months half are dead, and the effect is worse than having nothing at all.

Two solutions: choose species that can handle neglect —they are in plants that are almost impossible to kill— or hire a subscription with maintenance, which is the standard format in medium and large offices.

Where we stand

We sell plants and flowers for offices, and we still will not tell you they solve productivity. What they do is well documented: they improve how a space feels and how visitors perceive it. For a reception area, that alone justifies the expense, without needing to make anything up.
