On August 31, 2020, The Duke and Duchess of Sussex visited the Preschool Learning Center in Los Angeles and spent a morning gardening with young students, which is an annual activity that the school does every year. August 31 is also the 23rd anniversary of the death of The Duke's mother, Princess Diana. In order to memorialize her, The Duke and Duchess planted forget-me-nots, the late princess's favorite flower, in the garden of the school.
