Tomato plants are vines, initially decumbent, typically growing 180 cm or more above the ground if supported, although erect bush varieties have been bred, generally 100 cm tall or shorter. Indeterminate types are `tender` perennials, dying annually in temperate climates they are originally native to tropical highlands, although they can live up to three years in a greenhouse in some cases. Determinate types are annual in all climates.
