Darren Rudge and Helen Wood want their creation to show how an outdoor space evolves and is influenced by past and future.
"The garden is inspired by the space-time continuum, where events of the past and plans for the future meet in the present," Rudge explained.
Continuum will include honeysuckles, Clematis and Hydrangea, while recycled materials - scaffold cladding for fences - will demonstrate influences of the past.
"The sense of history is also echoed in the flora and fauna," Rudge said. "Plants such as the living fossil Ginkgo biloba Award of Garden Merit hark back to the time of the dinosaurs."
He added: "Gardens have a future, too, and Continuum has ramps in place of steps in preparation for old age."
The design is sponsored by Timberland and Marshalls. Other sponsors include Broadway Construction, Codsall Stone & Paving and Wolverhampton City Council.
Rudge and Wood, lecturers at City of Wolverhampton College's Cedars Horticultural Centre, also helped students with designs for a Birmingham Borders competition.
