St George’s Chapel in Windsor is filled with the smell of roses and other blooms used by floral designer Rob Van Helden to bring the season into the church.
The steps leading up to the chapel’s west door, where Princess Eugenie will arrive, are lined by a cascading display of roses, spray roses, hydrangeas, dahlias and berries.
The flora has a backdrop of Liquid Amber trees, giving the feel of a wooden glade soon to fall dormant when winter arrives.
Inside the chapel, the seating in the nave faces the aisle - unlike the Duke and Duchess of Sussex’s wedding where guests faced forwards.
More red, pink and purple blooms have been arranged either side of the organ screen entrance that leads from the nave into the quire where the wedding service will take place.
The last few metres of the central aisle leading up to the altar are also lined with more flowers, bringing the scent of blooms to the heart of the ceremony.
A palace spokeswoman said: “The designs reflect the rich and vibrant tones of autumn.”
Mr Van Helden said: “It has been the greatest privilege and honour to create the flowers for Princess Eugenie and Jack on their wedding day.
“Her Royal Highness has been very involved from the start and has been instrumental in the autumnal theme.
“The whole floral design team and I wish Princess Eugenie and Jack our heartfelt congratulations and we hope they have a magical wedding day.”
One of London’s top florists, Mr Van Helden was born and grew up in Holland, and moved to the capital 31 years ago.
He first started his floristry business from the back of his car.
