Across the world, chefs, farmers, plant scientists and backyard growers are doing something extraordinary: creating new generations of fruit, vegetables and cereals, all bred specifically to flourish locally, taste delicious, and contribute to our food future. Adam Alexander dons his seed detective homburg to meet these 21st century seed heroes, who are not only championing traditional varieties but also breeding delicious new ones that will help create a sustainable future for our planet. We don't all need to become backyard breeders or even, like Adam, accidental ones. We don't even need to eschew, as growers, the modern hybrid cultivars our seed catalogues are stuffed with or, as consumers, boycott those same uninspiring specimens that populate our supermarket shelves. Adam just wants that choice to be better informed and infinitely more diverse and enjoyable.
