The original pink variety has been grown commercially for 20 years and has sold millions worldwide, said managing director Robert Wharton. He said landscape architects are showing interest in the range and that he is in initial talks with Olympic landscapers about them using Flower Carpet 'Gold' roses at the event.
The Norfolk firm grows over 100,000 Flower Carpet rose plants each year. Production is being increased ready for the extra demand from the landscape trade in the run-up to 2012.
Wharton said Flower Carpet 'Ruby' will be available this autumn and a bright red variety will be launched in 2010. He added that buyers are looking for pot-grown patio roses for summer planting, with fragrance a key element.
Pot-grown plants are sold in garden centres where colour labelling has been improved with the change to large "pot-slot" labels.
Noack Roses in Germany is the breeder of Flower Carpet roses.
