On Sunday, May 16, beginning at 1:30 pm, enjoy a free lecture at the Wellesley College Botanic Garden led by environmentalist and naturalist Katie Griffith. Explore how a flower’s shape and color attracts the right pollinator for the plant. Dress appropriately for going outdoors, and children are encouraged to attend, accompanied by an adult. Pre-registration is required by calling 781-283-3094, or by emailing horticulture@wellesley.edu.
