Give a man tomatoes, feed him for a day. Give him the seeds to grow them, and he’ll frolic in a rainbow-coloured field of this tasty heirloom variety forever. This mix includes purple, green, red, pink, yellow, black, orange and a white variety, all of which were originally grown by Thomas Jefferson, the USA statesman and experimental farmer. Follow his lead and stake them for support. This beefsteak mix has been described as “super cool” (by us) and its flavours range from mild, to sweet, to tangy. Heirloom tomatoes are fragile and bruise easily, so they should be used immediately upon ripening.
