In 2021, WCG expanded our mission from solely managing community garden plots to building out and maintaining a more robust pollinator pathway among public land. These pollinator gardens are represented by butterflies on the map.

  • What's a pollinator pathway? Why do they matter?

     A pollinator pathway is a connected network of pollinator-friendly gardens, native plantings, and green spaces that provide continuous food and habitat for bees, butterflies, birds, and other beneficial insects.  


    By linking together backyards, community gardens, parks, schoolyards, and streetscapes, our plantings create "stepping stones" that help pollinators safely move through neighborhoods and urban areas.

  • How can I do my part to support them?

    Even small actions — planting native flowers, reducing pesticide use, or adding a few host plants — can become part of a larger, connected habitat that benefits both wildlife and the community as a whole.


    Join us at our events to support our public pollinator gardens, roadside gardening, the Watertown-Cambridge Greenway, and other pathway-sustaining projects!

OUR Public Pollinator Gardens

WCG currently maintains four public pollinator gardens in Watertown. Explore each of them below.

At Fillipello Park

Location: Filippello Park Butterfly Garden


Description: Three (3) raised garden beds surrounding the splash pad containing native and ecologically beneficial plants. Plant species were selected to attract butterflies, caterpillars, bumblebees and native bees rather than honeybees and wasps due to the proximity to children's play areas. WCG volunteers planted this garden in collaboration with the City of Watertown DPW in Fall 2021.

  • What plants live in this garden?

    Garden Bed 1 (north of splash pad):

    • 4 milkweed species (Asclepias)

    • golden alexander (Zizia aurea)
    • goldenrod (Solidago)
    • asters (Aster)
    • beebalms (Monarda)
    • hyssops (Agastache)
    • coneflowers (Rudbeckia, Echinacea)
    • beardtongues (Penstemon)

Roadside Gardening for Pollinators

We can "green up" our city’s unused spaces, and create valuable wildlife habitat. By planting native plants in the city-owned planting strip or bump-out (curb extension) in front of your own residence, you'll help migrating and local birds, butterflies, and bees.

Download WCG's step-by-step guide to planting in strips and bump-outs.

Other Roadside Gardening Resources

  • Read the Department of Public Works' Planting Strip Guide that highlights important city guidelines, native plant suggestions, and lay-out designs. This and more useful information is available at the Forestry Department's webpage.
  • View a presentation on how Melinda Dennis, a Watertown Community Garden board member, converted the bump-out in front of her residence on Hosmer Street into a vibrant pollinator garden.


If you do plant, please let us know. We would love to hear from you!

Life-Friendly Garden Tours

Are you concerned about chemicals in the home and garden? Or thinking about ways the green spaces in Watertown could benefit you and the environment? Or would you just like to visit some wonderful gardens? We’d love for you to join our annual tour celebrating life-friendly home gardens: spaces that haven’t been treated with chemical pesticides, herbicides, or fertilizers for at least a year.


This beloved tour was founded by Watertown Citizens for Peace, Justice and the Environment. In recent years we have co-hosted the tour with the WCPJE working group, Friends of Bees. We’re thrilled to welcome their team to WCG as we continue our shared commitment to supporting pollinators and healthy gardens for a thriving local ecosystem.

Watertown-Cambridge Greenway Stewardship

The Watertown-Cambridge Greenway is both an important pollinator pathway and a community treasure. Completed in 2022, it connects East Watertown to the Fresh Pond Reservation in Cambridge, providing a critical link between significant pollinator habitats at the Charles River, Mount Auburn Cemetery and Fresh Pond Reservation.


With this new green area comes stewardship to maintain a safe habitat for us and the wildlife that sustains the environment. Our Greenway volunteers work to remove invasive plant species, plant native plants, remove litter, and provide ongoing care to this critical link.

POLLINATOR PATHWAY EVENTS

We hold fun events with major impact. Our events include activities like:

  • Public garden cleanup
  • Planting native plants
  • Weeding and removing invasive species (such as black swallow-wort)
  • Knowledge-sharing sessions, tours, and demonstrations for life-friendly gardening


Our upcoming pollinator pathway events are listed below.

By Lori Shapiro  Spring has, finally and gloriously, burst. The warmer, longer days are driving the emergence of stunning spring flowers. The delightful weather and colorful blooms may motivate you to finally buy those seeds you have been thinking about. But summer is fast approaching, and you have so many demands on your time, and the easiest and fastest way to buy some seeds is with a couple quick clicks on Amazon. What could possibly go wrong? These very relatable sentiments were expressed by a colleague as she excitedly showed me a package of sweet pea seeds she had recently ordered on Amazon , as visions of delicious homegrown spring peas delighted her imagination.

WCG wants to help gardeners in the community grow the best plants for pollinators and diversity of local wildlife! Now is the time to be planning our gardens, and planting native plant seeds! Turning gallon jugs into mini-greenhouses is a great way to grow your own plants, a method called “winter seed sowing”. We have instructions for this method here: Winter Seed Sowing Basics - WCG.pdf Seeds that require 30 days or fewer of cold stratification (exposing seeds to cold, moist conditions to break dormancy). Even though snow is melting, seeds can still be stratified in temperatures between 34 and 40 degrees Fahrenheit.
