This story explores the growing trend of 'pocket gardens' - small, intentionally designed green spaces in urban areas that provide a range of benefits, from improving mental health and reducing air pollution to mitigating the urban heat island effect and absorbing stormwater. Pocket gardens are engineered to maximize the impact of vegetation, using native plants that attract pollinators and require less maintenance. These small green oases are transforming the look, feel, and function of cities.

Why it matters

As cities grapple with the challenges of climate change, urban density, and declining public spaces, pocket gardens offer a versatile solution that can address multiple issues at once. By incorporating more greenery into the built environment, cities can improve public health, increase biodiversity, reduce infrastructure strain, and foster community connection.

The details

Pocket gardens are ornamental green spaces, often tucked into underutilized areas like sidewalks, hospital grounds, and campuses. They are engineered to maximize the benefits of vegetation, using native, drought-tolerant plants that attract pollinators and require less maintenance. The vegetation in pocket gardens helps scrub urban air of pollutants, releases water vapor to cool the surrounding area, and absorbs stormwater to reduce pressure on sewer systems. Mixing tree species also builds biodiversity and resiliency. Beyond the environmental impacts, pocket gardens encourage people to get out of their cars and gather in public spaces, promoting physical activity and social connection.

  • Pocket gardens have been popping up in cities across the U.S. in recent years.
  • A recent study in Barcelona found that after the development of 'green axes' with pedestrianized spaces and vegetation, average noise levels fell by 3.1 decibels.

What they’re saying

“This increasing prioritization of creating green spaces in unexpected spots and underutilized spaces in communities is not only going to be making our communities more resilient, it's going to be making people healthier.”

— Dan Lambe, Chief executive, Arbor Day Foundation

“It's actually a transition toward the pedestrian — toward the person — and away from the vehicle.”

— Eric Galipo, Director of campus planning and urban design, FCA

“If people see green in general, the noise perception tends to change. You think that things are not as noisy as they actually are.”

— Samuel Nello-Deakin, Postdoctoral researcher, Autonomous University of Barcelona

What’s next

Cities across the U.S. are continuing to invest in and expand their networks of pocket gardens and other small-scale urban green spaces to address a range of environmental and public health challenges.

The takeaway

Pocket gardens are proving to be a powerful and versatile tool for cities to improve quality of life, foster community, and build resilience in the face of climate change. By strategically incorporating more greenery into the urban landscape, cities can unlock a wide range of benefits that extend far beyond just aesthetics.
