Buckingham Garden Centre's Chris Day said it was stocking one-third blue spruce, one-third Nordman and one-third noble fir to provide a point of difference.
Meanwhile, Pines and Needles forecasts 50 per cent more sales this year. The London-based company, founded by Sam and Josh Lyle in 1994, expects to sell £3.2m worth of trees harvested from their father's farm at Dunkeld, Scotland.

Irish minister Andrew Doyle has urged people to buy a real Irish Christmas tree this year as he visited Stephen Cowman at Parkmore Christmas Tree farm in Moneystown, Co. Wicklow. "At home we always make sure we have a real tree. It wouldn’t be the same Christmas experience without a real tree and all that goes with bringing it into the house, setting it up, the smell and the atmosphere.
"I see the Christmas tree farms around the country especially here in Wicklow and the 7 to 10 years work that goes into producing a good quality tree – the work is all year round, planting, shaping, spraying, fertilising, marketing, harvesting."
Around 550,000 Christmas trees are sold in Ireland each year with 350,000 sold at home and about 200,000 trees exported to the UK, France and Germany. The industry is worth €21 million to the Irish economy.
