On Monday, the mother-of-three will go on display with Her Majesty on hand to support her during the big reveal.
The Queen will attend the first day of the annual flower show along with several other members of the royal family.
On Monday Kensington Palace shared never-before-seen photos of Kate prepping for the flower show, which she co-designed with the Royal Horticultural Society and award-winning landscape architects Andrée Davies
"She is very hands on, model making, emailing images, coming up with all the ideas that we want to capture,” revealed Andrée.
“She would often bring a folder of cuttings with her full of ideas. The Duchess was very keen to use natural materials, has a clear idea of the colour palette she wants and her desire to incorporate the natural elements."
