Why office plants really do boost productivity – backed up by evidence
For years, the ‘lean’ office movement has encouraged companies to clear their workspaces of anything that wasn’t strictly functional, including plants. Research in occupational psychology now suggests the opposite: office plants measurably boost productivity, and it’s not just a matter of decoration.
What the benchmark study shows
A team of researchers from the Universities of Exeter, Cardiff, Groningen and Queensland (Nieuwenhuis, Knight, Postmes and Haslam) published a paper in 2014 in the *Journal of Experimental Psychology: Applied, three field experiments carried out in real commercial offices in the Netherlands and the United Kingdom. The result: simply adding plants to a previously spartan office increases productivity by 15 per cent.
The benefits extend beyond productivity. Teams working in green spaces also reported higher job satisfaction, lower levels of disengagement, and an improved perception of air quality, even when the air quality had not objectively changed.
Why it’s not just a matter of decor
The common belief is that a plant brightens up an office without affecting the work itself. The researchers behind the study explain a different mechanism: what matters is the perceived enrichment of the space and the sense of autonomy that staff derive from being in an environment designed with them in mind, rather than one that is merely functional.
This also explains why a single plant tucked away in a corner does not have the same effect as plants spread throughout the workspace. Our article on how to approach colour in your spaces discusses a similar psychological mechanism: that of an environment perceived as well-maintained rather than one that is simply endured.
How to effectively introduce plants into an office
Choose plants that are suited to the actual light conditions in the office, not to the desired aesthetic effect. A plant that is withering has the opposite effect to the one intended.
Spread the plants out across several areas rather than concentrating them in a single decorative corner. The effect measured in the study stems from a diffuse enrichment of space, not from an isolated focal point.
Opt for a green wall in areas where individual maintenance is not possible. Open-plan offices, reception areas, meeting rooms: a living wall maintains the effect without relying on people’s goodwill.
Involve the teams in choosing the tree species or the layout. The sense of autonomy is part of the mechanism documented by researchers, not just the presence of green.
Maintain it over the long term. A neglected plant or a poorly maintained green wall sends the wrong message to staff about the care taken with their working environment.
What Wooh has to offer in this regard
Green walls are one of the finishing solutions offered by Wooh, alongside partition walls, acoustic solutions and flooring. The team supports businesses from the choice of plant species right through to maintenance, taking a holistic approach to interior design rather than treating it as an isolated decorative feature. Find out more about this solution on our living wall page, or explore other approaches in our article on office trends for 2026.
Frequently Asked Questions
How many plants are needed per office to achieve a measurable effect?
There is no universal threshold. The benchmark study shows that an effect is observed as soon as an otherwise empty space is enriched; the exact quantity is less important than its widespread and sustained presence.
Does a living wall have the same effect as a plant on a desk?
The mechanism described (perceived enrichment, autonomy) applies to both, but a living wall ensures a continuous presence without relying on individual maintenance by each employee.
Do artificial plants work just as well?
The studies focus on real plants. An artificial plant may have aesthetic benefits, but there is no evidence to suggest that it replicates the effect observed on productivity and well-being.
How much maintenance does a green wall in a business require?
It depends on the system chosen (hydroponic, semi-automated) and the plant varieties. Wooh offers support, including maintenance, to prevent the system from deteriorating over time.
