Boston Building Resources (BBR), in Boston, Massachusetts, will host a free, family-friendly celebration of the Earth with live music, free food fresh from the grill, a plant swap, tie dye station, prizes, kids’ activities and tips on saving energy from 11 a.m. to 2 p.m. on April 26.

Attendees will be able to share their favorite perennials and take home new ones for this year’s garden. Organizers ask that attendees refrain from bringing any plants that are considered invasive or have signs of pests or diseases.

The BBR—a consumer co-op and nonprofit reuse center—strives to inspire, educate and empower homeowners to enhance the efficiency and value of their properties, while also offering affordable solutions that benefit the community as a whole.
