Kelvedon expanded significantly in the Victorian era. The reason was the Norwich to London railway making it a place to live yet get to work as rail was the only fast method of transport. Victorian Kelvedon was set along one street, High Street. In the late 19th century, Kelvedon became famous for seed growing, and the firm of Kings Seeds, now part of Associated British Foods, became famous for the production of flower and vegetable seeds. Another large seed merchant, based nearby in the hamlet of Inworth, and trading worldwide was E W Deal & Sons (a founder member of Asmer Seeds based in Leicester) who were famous for developing the Kelvedon Wonder Pea and other varieties of flowers and vegetables.
