Celebrity are determinate IIRC....I really have gone back to the good ol beefsteak tomatoes....celebrity and better boy (?) are good to get early tomatoes....also, I like the larger cherry tomatoes as well...
Mine get pretty huge & I get tomatoes until frost (often end up bringing in green tomatoes so they don’t freeze). I think “semi-determinate” is a good description:
Celebrities are almost entirely maintenance-free. No trimming, pruning, or grooming is necessary and the plants will grow up to five feet high (depending on your soil depth and conditions). They are often called semi-determinate, which means that the tomato plant and bush grows to a certain size and doesn’t get any bigger like a bush / determinate tomato plant. But it keeps giving you new tomatoes all the way until the first frost, like a vine / indeterminate tomato. That’s why they don’t need pruning.
