This year’s Lilac Sunday T-shirt was designed by the Boston Architectural College Student Chapter of the American Society of Landscape Architects. Olivia Fragale, a 2014 Hunnewell Intern at the Arnold Arboretum’s plant propagation and nursery facility, led the initiative and worked collaboratively with the Arboretum’s Lilac Sunday organizers and printer Evan Webster of Evan Webster Ink in Shelburne, Vermont. Celebrate spring at the Arboretum on Lilac Sunday, May 10, 2015.
