Paul Hervey-Brookes' garden will be brimming with spring plants and is sponsored by Wyevale Garden Centres. Hervey-Brookes, who works at Wyevale Garden Centre in Nailsworth, Gloucestershire, will compete in the Chris Beardshaw Mentoring Scholarship scheme.
"This is really exciting as I have the opportunity to create a garden with a real wow factor," he said of the 35sq m patch he will transform from late April.
Plants with purple and silver flowers and sculptural foliage will include Tulipa, Allium, Geranium, Dryopteris and Betula.
One area will include open wild woodlands with hornbeam and maple under-planted with native ferns, shrubs, nettles, dock and bluebells.
The second area will be formally laid out with four beds, representing the seasons, around a sculpture with arbours for reflection.
His garden is one of 12 entered into the Beardshaw Mentoring Scholarship, set up in 2007 to encourage good design.
Hervey-Brookes trained at Royal Botanic Garden Edinburgh and won a silver gilt award at the Malvern Autumn Show last year.
