From Secret London website:
“To celebrate the festive season, Grosvenor Square has transformed into the Ever After Garden: a beautiful space filled with over 27,000 illuminated white roses. Visitors can plant roses in memory of loved ones they have lost – and the cost of each rose will help to raise funds for The Royal Marsden Cancer Charity.
Designed by Anya Hindmarch and Camilla Morton, in memory of their friend and top Production Designer Michael Howells, the Ever After Garden is a stunning and peaceful way to commemorate the people we have lost. The installation has been developed by Culture Creative, the same award-winning design team behind Christmas at Kew Gardens.
November 29 – December 22 (12pm – 8pm, each day)
