I've grown a very purple tomato

On that Note. Other tomatoes of that plant are less purple. Would it make sense to save seeds from just this one or is that not how it works?

Saving seeds from your purple tomato makes sense, but the resulting plants might not always have the same vibrant color. Tomatoes can show a variety of traits due to genetic diversity, and factors like genetics, environmental conditions, and soil can influence the next generation.

To increase your chances of getting more purple tomatoes, save seeds from several tomatoes with similar traits. Keep in mind that cross-pollination can affect the outcome. For more controlled results, consider isolating the plant or flowers to avoid cross-pollination with less purple tomatoes.

You could also take the plant to a professional nursery; they might be interested in buying it from you.

The tomato is so purple, it might just turn into a superhero, lol!

That’s not quite how it works. The chemical that makes tomatoes purple is produced by the strain, and in gardens, it’s typically activated by sunlight.

Naturally pollinated tomatoes grown outside are likely hybrids, so they won’t grow true to type.
