The erotic novel has sold more than 1m copies since publication earlier this year.
Partner Barry Hall said: "It's about raising female awareness because of the book and the display we've done linking to the book. About 83 per cent of our customers are female so we thought this was a good idea."
A garden centre representative said:
"Obviously this book is causing quite a stir amongst of lot of ladies out there and whether you have read it or not it is hard to avoid its attention and impact.
"The scene we have displayed at Littleheath has gained a lot of interest and more than a few raised smiles. Customers are stopping in their tracks and have even tried to read the books. We are always looking at new innovative and fresh ideas to make our garden centre interesting and up-to-date grabbing our customers attention."
