Prince Harry and Meghan Markle have honoured Princess Diana’s memory by planting her favourite flower, forget-me-nots, according to reports.

On Monday, the 23rd anniversary of the late royal’s death, the Duke and Duchess of Sussex visited the Preschool Learning Centre in Los Angeles, California, where they helped the children plant flowers in their garden.

In addition to forget-me-nots, the couple also planted petunias, California wildflowers, tomatoes, squash, and other plants.

In photos shared by children and women’s charity Assistance League of Los Angeles, the duke and duchess can be seen dressed casually in jeans, button-downs and masks while they dig in the dirt and water the flowers alongside the children.

“The children of our Preschool Learning Centre got a wonderful surprise when The Duke and Duchess of Sussex visited yesterday!” the charity wrote on Instagram. “In addition to helping the children replant the Preschool Learning Centre's garden, they spent time with them, sharing their appreciation for nature and helping to instil the importance of healthy eating.

“We truly appreciate their time and care for our students.”

According to royal biographer Omid Scobie, who shared that the couple planted forget-me-not seeds in honour of Prince Harry’s mother on Twitter, the duke and duchess also played nursery rhymes in the garden and read books to the children about gardening, vegetables and planting during the visit.

Scobie also revealed that Prince Harry and Meghan have previously volunteered at the centre.

This is not the first time the couple, who recently relocated to California after stepping down from their roles as senior members of the royal family, have paid tribute to Princess Diana’s memory with her favourite flower.

In 2018, Meghan included forget-me-nots in her wedding bouquet. The flowers were also featured in the backdrop of an Instagram photo celebrating the duchess’s first Mother’s Day in 2019.

Earlier this week, Kensington Palace announced Prince Harry and his brother Prince William have commissioned a new statue in honour of their late mother, which will be installed on what would have been her 60th birthday.
