Is it possible the plant was marked incorrectly? We brought home seedlings one time that were supposed to be cantaloupe and we got a lovely crop of okra.
Very possible (though it’s certainly some kind of tomato).
The shame is I had great success with my first heirloom Beefsteaks last year and saved the seeds... and then accidently threw them away.
Hoping to see some sprouting up from where last year’s tomatoes were, no luck so far.
Mis-marked vegetables generally occur near the end of the planting season .
Frequently , customers will pull a marker our of the flat , forget where it came from , and put it somewhere where is is convienient (to them).
Growers and greenhouses don't purposely mis-mark crops as it ruins their reputation, and turns buyers to go elsewhere.
