Tomato Terminology

It can be helpful to understand some of the following terminology as you shop tomato varieties.

  • Growth Habit
    • Indeterminate: vining-type tomatoes that continue to form new leaves, shoots, and flowers for an indefinite time period (until frost or some other factor causes them to die).
    • Determinate: bush-type tomatoes, which grow to a certain size then divert their major energy stores away from vegetative structures, toward flower and fruit development and ripening.
    • Semi-Determinate: tomatoes that continue growing like an indeterminate, but maintain a more compact, bush-like plant, like a determinate.
    • Dwarf or Semi-Dwarf (a.k.a. Patio Tomatoes): these plants have a tidy plant habit and short stature generally appropriate for container growing.
  • Greenhouse Performer: varieties demonstrating outstanding performance in protected agriculture including greenhouse or high tunnel/hoophouse. For more on our trial criteria and specific variety recommendations for the heated greenhouse and unheated tunnel, see Trial Criteria for Johnny’s Greenhouse Performers.
