Retail salesman Mark Smith said trolley sales during the two days topped 350, with more than 500 trolley orders being received since the event.
He explained: "Last year if I was trying to get someone to visit the nursery, it was easy for them to say no because imported stock was seen as more expensive. But if you show them a plant that looks great for 50p more they are still going to buy it so it is just a case of trying to get them here."
Owner Renato Canale said the company was hit hard by the exchange rate but insisted price was not everything. He said demand for large specimen plants in garden centres had been the hardest hit by the recession but that confidence was coming back.
"We are actually selling many more smaller size plants that in the past we used to neglect. Now we are selling Euonymus five-litre, Buxus five-litre, Bamboo 10-litre, Bay three-, five- and seven-litre.
"We would normally just show bigger plants."
