Welcome!

LexCAN is a Lexington-local climate action and advocacy group. We work with partners and collaborators for meaningful change. Join our movement!

The Give Grass a Chance Campaign was Successful!

Thinking Globally, Working Locally

Through a variety of interactive & educational programs organized to help our community work through the most urgent and necessary changes.

Helping Residents Electrify Everything

LexCAN works closely with the Town of Lexington's sustainability team to create programs like Clean Heat Lexington.

Reducing Waste and Protecting Ecosystems

We work closely with many local partners like LexZeroWaste, Lexington Living Landscapes, and many more organizations for maximum impact.

Advocating for Policy Change

LexCAN has helped turn climate ideas into town bylaws — including the nation’s first gas-powered leaf blower ban and a law banning fossil fuels in new home construction. Advocacy isn’t just talk.

Lexington Living Landscapes’ Open Gardens Day

June 21st 2025 | 10:00 am - 3:00 pm

Come Meet and Learn from Other Lexington Gardeners!

More and more homeowners are embracing landscaping that emphasizes native plants and organic methods to create more wildlife- and people-friendly yards. Are you curious to see what other gardeners have done? Stop by any of multiple locations to see the many forms a pollinator garden can take or learn what alternatives to the traditional lawn fellow residents have tried.

The homeowners involved are generously opening their yards to visitors in the hopes that you’ll see something that will help or inspire you in your own landscaping, and to learn from you as well.

Six different gardeners are participating each week, and each property will be open to visitors either from 10 am–1 pm or 1-3 pm that day. Visit as many or as few as you wish. No ticket or pre-registration is needed.

A detailed schedule and map of participating properties will be available the previous Sunday at www.lexingtonlivinglandscapes.org.
