The company said college trainees let loose on the site this summer inundated the landscapers with plant list requests. It worked with web designer Bluespark on the launch of willer.co.uk.
"During the Olympics students were asking our guys for more details on planting and design," said manager David Witham. "We decided to take photos and highlight plant names online."
Willerby Landscapes flagged up other landmark projects such as work at Canary Wharf and Liverpool One. It is also building Robert Myers' 2013 Brewin Dolphin RHS Chelsea Flower Show garden.
"This follows months of careful planning and design. Highlights include a page for horticultural students to enable them to download project portfolios and learn more on how the works are completed," added Witham.
"Our website was seven years old and no longer showing where we were positioning ourselves. We wanted to explore using case studies and QR codes to enable plant pallets and descriptions to be uploaded to mobiles.
"The job of constructing and maintaining the Olympic gardens can now be shared via a dedicated case study that gets into the detail of the challenges faced."
