Plant graduation season, an annual rite of passage at the Arnold Arboretum of Harvard University, is an occasion for pomp and circumstance as well as a reminder of our connections to nature and the power of plants. The Plant Graduation Class of 2021 took place on April 2 and featured more than 500 plants, some rare and endangered, graduating from the nursery and finding placement throughout the 281-acre landscape of the free and open museum teaching the world about plants. Before the plants officially graduated from the greenhouses for their new “careers” out in the field, a commencement ceremony was held to honor the budding and burgeoning Class of 2021. “The fact that there are more and more plants being planted and groomed and protected and nourished shows the importance of this place," said District 6 City Councilor Matt O'Malley. “At the Arnold Arboretum we do conservation, education, and we are trying to make sure people understand their responsibilities to the planet and to their fellow species,” added Ned Friedman, Director of the Arnold Arboretum.
