With the NFU pulling out of its UK Horticulture exhibit at the RHS Chelsea Flower Show and more publicity for hobby growers than professionals as well as for promotions that use more overseas-grown flowers, Lamb said she feels that professional UK growers do not get the recognition they deserve.
She said: "There's a large amount of interest in home-grown cut flowers but there's a difference between artisan growers and artisan growers trying to make a living out of it."
The £4m-turnover grower said the public does not know that tulips are locally grown because "they don't have the local workforce and these things are not talked about at the school gate".
Lamb supplies Waitrose through Butters, Asda through IPL and Morrisons with cut flowers such as stocks, tulips, Lisianthus and antirrhinums. She said Waitrose would always go British where it could, though the UK cut-flower industry has been hit by the exchange rate. She hopes to supply Interflora in 2016 at Chelsea after being the only British supplier out of 60 on the flower company's 2015 Chelsea stand.
