Called Moodboard, it acts like those used by planners and designers that include an array of ideas, jottings, rough sketches and magazine clippings pinned onto a board to help find inspiration when working on new ideas. The new app allows designers and customers to do this on an iPad.
Group marketing director Chris Harrop said: "It's designed to help people get inspiration. The iPad has only been around for about two months and it's revolutionised technology. We think that our application will change the way that landscapers interact with visual ideas."
The application, which is available to download for free, has been designed by digital creative agency Dolphin. It contains many illustrations and pictures of flowers and landscaping features to give ideas to customers.
There are four garden themes - a vegetable garden, a tranquil garden, a children's play garden and a garden for socialising.
The application contains a "Make it Happen!" button, which immediately puts people in touch with suppliers and landscaping firms. Although all the firms listed are Marshalls stockists, the application can be used to give ideas on materials from any supplier.
