Fun facts

  • Botanically the tomato is a fruit — a berry — though the US Supreme Court ruled it a vegetable for tariff purposes in 1893.
  • Tomatoes were once feared poisonous in Europe and grown only as ornamentals, earning the nickname "poison apple".
  • Determinate varieties grow to a set size and ripen all at once, while indeterminate varieties vine and fruit until frost.
  • China is by far the world's largest tomato producer, growing tens of millions of tonnes annually.
