He said: "We have always grown large numbers of poinsettias here at the garden centre, which is part of the Garden Centre Group, but this year we have 50,000 growing on, which is 5,000 more than 2008.
"We started ordering the plants back in March and they arrived in June as tiny cuttings. We will sell around 7,000 direct to the general public who visit the garden centre. We also supply the plants to other garden centres in The Garden Centre Group."
The centre grows ‘Infinity', ‘White Glitter', ‘Mars' and ‘Picasso'.
The Garden Centre Group, formerly Wyevale, believes it can grow one-third of the plants it sells itself.
Chief executive Nicholas Marshall said the demand for British-grown plants was driving the move. The strong euro and the desire to use spare land has also prompted the change.
The grower charged with building up the proportion of plants the Garden Centre Group grows for itself, former Notcutts grower Paul Masters, has left and been replaced by Garden Centre Group regional store manager Alyson Haywood, the former Woodlands centre manager.
Imports of poinsettia are believed to be down this year because of the euro, with British growers taking up the slack. But there has been issues with Bemesia for some growers this year as pesticides come off the market.
