The design is based on the ripples from a drop of water and features three discs planted with a mixture of New Zealand native perennials and shrubs, with a single central tree surrounded by the engraved pebbles.
Hervey-Brooke's The Moment with Yealands Family Wines garden is one of a record 16 major gardens at this year's Ellerslie International Flower show.
Hervey-Brookes is collaborating on it with Yealands Family wines as they share similar environmental values and goals.
Trained at the Royal Botanic Gardens in Edinburgh, Hervey-Brookes now creates gardens in Britain and many other countries.
After Ellerslie, he will design and lay out a Main Avenue Garden at the Chelsea and launch a new series of his popular gardening gifts for British retailer Marks & Spencer.
Ellerslie International Flower Show is in Christchurch's North Hagley Park from February 26 to March 2. Tickets are on sale at www.ellerslieflowershow.co.nz. Earlybird $29 tickets are available until February 9.
