Recreating an authentic historic walled kitchen garden will require old varieties and cultivars. Fortunately there are now a number of specialised suppliers of plants and seeds, too numerous to list here. The HDRA Heritage Seed Library is a good start: www.hdra.org.uk/hsl/ HDRA and some of the other national organisations linked to the Walled Kitchen Gardens Network can generally advise their members on sources of plants and seeds. See also Heritage Vegetables under publications.
