Gardening Express (see our Mail Order Section) have become the sole on-line distributor for 'Carroll's Hertitage Seed Potatoes'. This is a company, based near Berwick-upon-Tweed, whose mission it is to grow and promote unusual varieties. These include the likes of 'Edzell Blue' and 'Pink Fir Apple'. Gardening Express are keen to point out that the varieties offered provide a full crop and need no special care. Chris Bonnett of G.E. says 'We're doing our bit to preserve our national heritage and traditional varieties at the same time, as many of the varieties are on the endangered list'. The seed potatoes are certified by DEFRA.
