People have always had office plants, but now certain companies are taking it to a whole new level. Millennials love plants, and wellness trends. Combine that with business' incentives to make offices comfortable and appealing to millennials, and that's where living wall installations come in. Serene Buckley of Habitat Horticulture says logo walls are a particularly hot trend for tech companies, and that millennials purchase species of plants like monstera and pothos with a frequency older generations haven't. Science has shown that having plants around is a good thing, as they clean the air, can absorb noise pollution, and generally liven up the look of a space, making people happy.
