Alexandra Lehne and Momo Pino are recent students who received the postgraduate Diploma in Residential Garden Design from the Oxford College of Garden Design.
The pair have won a £6,000 commission to build a design at the Southport Flower Show.
The brief was to design a garden based on the show's theme of "Coast", in a 6m x 6m square plot.
Their garden will feature coastal planting, a pebbled terrace area, a pergola and shallow ponds.
Soft but structural grasses, perennials and shrubs are intended to invite visitors to rest and relax.
The Southport Flower Show is from 19-22 August.
