‘Volunteer Tomato’ Neat name for a Tennessee Tomato.
The answer to your question - a definite - maybe.
If it grew from a hybrid seed, it has a 50% chance of being a hybrid and a 25% chance of the true parent A and 25% chance of the true parent B that made up the hybrid.
The way to tell is going to be to observe the plants you start from those seeds. If they turn out true to the volunteer plant, they should be open pollinated.
Hope that helps...
That's what I was afraid of. Even so, I'm going to plant them and see what I get. I can't wait to see what they do now!
