Marathon Daffodils is in its fifth year of growing and delivering thousands of daffodils throughout Boston and along the Boston Marathon route.

Marathon Daffodils is an annual program founded in 2014 by Diane Valle, a passionate urban horticulturist, to bring beauty and a symbol of hope to the Boston Marathon following the 2013 bombing.

Valle envisions Marathon Daffodils as tribute to Boston Strong. The program collaborates with hundreds of donors and volunteers who donate their money and time to add the cheerful display of yellow daffodils, which welcome the runners, visitors, residents and workers.

“Our goal is to provide this living symbol of hope, spring and rebirth,” said Clive Olson, Jr., the Marathon Daffodil vice president.

“Marathon Daffodils are used to remember those who lost their lives; to acknowledge those who suffered injuries and those who rushed to their aid; to lift the community spirit, and to signify the resilience and strength of our entire Boston Strong community,” said Matthew J. Piscitelli, a grower of the daffodils.

Last October, more than 25,000 Dutch Master daffodil bulbs were imported from Holland, planted in 5,000 pots and put into a massive cooler at Olson Greenhouse in Raynham. Three weeks prior to Marathon Weekend, the bulbs were removed from the cooler, ending their winter-long hibernation and beginning their life as a Boston Strong Marathon Daffodil.

On Friday morning, April 13, the trucks will be loaded while teams of volunteers gather at a dozen locations throughout Boston, waiting to receive the Marathon Daffodils.

The volunteers deliver the plants to stores, restaurants, businesses, greenspaces and doorsteps to celebrate the arrival of spring and to celebrate the greatest road race in the world.

“Come watch the remarkable runners; see the beautiful, cheerful, yellow Marathon Daffodils and enjoy our great City of Boston. Spring is finally here,” said Valle.
