The title is awarded by the Good Food Channel's Market Kitchen programme for businesses with good-quality produce and customer service as well as commitment and passion and a strong connection to their local area.
Food lovers across the nation were asked to nominate their favourite growers or farm shops. Edible Ornamentals beat off competition from 10 other East Anglian businesses and will now compete with the other nine regional winners for the chance to be named National Local Food Hero 2009.
Joanna said: "We felt honoured that our customers put us forward for this award and being voted East Anglian Local Food Hero is recognition of our passion for chillies and good wholesome fresh produce."
The Plumbs began growing chillies in 2001 and developed their own range of gourmet chilli sauces in 2004.
Their coverage on the Good Food Channel was the latest in a series of TV appearances on programmes including Ready Steady Cook and Economy Gastronomy.
The National Local Food Hero 2009 will be announced today (11 December) on the Market Kitchen show.
