The 144-centre chain now has three catering brands including Botanic Kitchen, a "brand new restaurant offering the garden on a plate" launching in early 2015, as well as Coffee Ground "micro-roasting artisan coffee shops" and Garden Kitchen Restaurants "bringing a sparkle".
WGC has opened two Coffee Grounds at Endsleigh and Hemel Hempstead garden centres with another in Beaconsfield opening this week and more to come in 2015.
The company has completed Garden Kitchen makeovers in 15 centres including Brighton, Syon Park, Nailsworth, Leicester Rowena, Stratford-upon-Avon and Enfield, with others to follow next year.
Costa Coffee concessions have opened at Melbicks, Cadbury, Dorking, Hungerford and World's End.
WGC food and beverage director Jason Danciger said:"There is a revolution afoot in garden centres across the country as food, service and environments take a leap forward."
Wyevale has bought the Podington, Trelawney Ashford and Raglan centres in the past month.
