Head of visual merchandising and retail space planning Craig Roman said home made wreaths, arrangements with bays, hellebores, dried hydrangeas and rosemary in terracotta was a trend. Emerald green is the "in" colour.
He said Dobbies was developing its own product and not just buying from Gisela Graham and Kaemlingk. The Dobbies range is separate from Tesco's. Christmas trees are from Aberdeenshire.
Roman, who was previously at Wyevale Garden Centres, added that Dobbies outlets are easier to plan than Wyevale because they are of similar sizes and layouts.
There are 25 'A' stores and 10 'B' centres. The 'B' centres have the width but not the depth of seasonal stock and keep bulbs and lawncase longer into the autumn.
Roman said many of the Christmas products were suitable for use all winter and were not specifically branded as Christmas goods.
Dobbies said it is continuing business as usual despite interest from Wyevale. There are no new stores planned.
Katharine Poulter has joined Hobbycraft and Steve Guy and Judith Harris have replaced her on Dobbies' management board. Guy is now horticulture and outdoor living buying and merchandising director, while Harris is non-horticulture and Christmas merchandising director.
