All tomatoes fall into one of two categories: Indeterminate plants bear fruit continuously up until frost; determinate plants set one large crop and are finished once it ripens. The numerous fruit types -- including currant, cherry, slicing, plum, and beefsteak -- may fall into either category. Heirlooms, whose seeds have been saved and passed on by gardeners, are frequently indeterminate.
Indeterminate plants have long, sprawling vines requiring heavy-duty staking; determinate plants are bushy and can be contained by tomato cages.
