Scoop the seeds from a grocery store tomato, plant them, and see what happens. Denise Massey did exactly that with an organic store tomato. Another grower, D Nikolls, had already done the same thing more than once, and few issues came up, whether the tomato was labeled organic or not.
Tyler Ludens, on that same thread, skipped the scooping step entirely. Slices of a store tomato went straight into the dirt, buried slightly, and the plants grew.
Grow tomatoes from store bought fruit and the seed usually cooperates. What comes up next is the real question. It depends on one detail most shoppers never think to check.
The short version
Yes, seeds from a store bought tomato generally germinate and grow into a real, fruiting plant. Real gardeners on permies.com report success scooping seeds, fermenting them, or simply burying a slice.
The catch is genetics, not viability. Most tomatoes sold in stores are hybrid varieties, according to University of Florida IFAS Extension. They are bred for shipping and shelf life rather than flavor.
Saved seed from a hybrid does not grow into a copy of the parent plant. It can throw a wide, unpredictable mix of traits instead, sometimes for the worse.
Why the seed usually sprouts just fine
William Schlegel, replying on that same permies.com thread, put the biology plainly. There is no real difference between saving seed from a store tomato and saving seed from one grown at home.
The scoop and ferment method works the same either way. This site’s full fermentation guide covers that process step by step at our how to save tomato seeds guide.
Bruce Fine, on the same thread, made a related point worth remembering. Organic on the label does not mean heirloom or open pollinated underneath it.
The catch nobody puts on the sticker
University of Florida IFAS Extension confirms hybrid tomatoes are the most frequently grown type of tomato worldwide. Fresh market cultivars get chosen specifically for firmness and their ability to survive shipping and storage.
Those same fresh market tomatoes are typically harvested green. IFAS Extension notes they get treated with ethylene gas afterward. That ripens them closer to the store shelf than the vine.
Real gardeners scooping seed from exactly that kind of gassed, hybrid grocery tomato still report normal germination. What varies is what grows once the seed sprouts, because a hybrid tomato is not a stable variety to begin with.
What a hybrid actually is
University of Illinois Extension explains an F1 hybrid as the deliberate cross of two different parent plants. The offspring carry one dominant version of many traits from each parent. That pairing is exactly why a hybrid tomato often out performs either parent alone.
That advantage does not pass down cleanly. Illinois Extension describes what happens when a gardener saves seed from that F1 fruit and plants it. Those paired dominant traits separate out in the next generation, and the recessive traits they had been masking can resurface.
University of Missouri Extension calls this reversion directly. Saved hybrid seed tends to drift back toward the traits of one or the other original parent. It rarely matches the tomato it actually came from.
What that segregation actually looks like
Joseph Lofthouse, a plant breeder active on permies.com, grew about seventy two second generation Sungold plants from saved seed. Roughly ten percent of the fruit came back red. That is not the variety’s signature orange.
He has tried reversing Sungold back toward a stable variety twice since then. Neither attempt recovered the original flavor in its descendants.
John Pollard reported a similar spread on the same thread. His second generation plants looked like three different varieties: a pink and red cherry, a medium pink, and a poor tasting yellow cherry.
Margaret Kennedy described the same drift playing out slowly across her own garden. Volunteer plants she suspected were Sungold offspring shifted toward more red fruit and fewer yellow ones every year.
Not every account went that way, though. Vashti Wood reported four generations of saved supermarket tomato seed growing into fruit that matched the original punnet almost exactly. Segregation is a real risk, not a guarantee.
So is it worth trying
Genetics aside, a plant grown from a store tomato’s seed is a real, fruiting tomato plant. It needs the same care as any tomato, covered start to finish in our guide to how to grow tomatoes. Denise Massey’s actual problems that season were heat and hornworms, not a seed that failed to become a plant.
If the store tomato happened to be heirloom or open pollinated rather than hybrid, saved seed grows true. This site’s guide to hybrid seed covers how to tell the difference. It also explains why open pollinated varieties like Brandywine breed true where hybrids like Big Boy do not.
For a hybrid tomato, the honest framing is an experiment, not a shortcut to grow tomatoes from store bought fruit and expect a repeat performance. The plant will very likely fruit. What it fruits into is the part nobody can promise in advance.
Frequently asked questions
Can you really grow a tomato plant from a store bought tomato?
Yes, and it works more often than people expect. Real gardeners report success scooping out the seeds, fermenting them, or simply slicing the tomato and burying pieces directly in soil. Germination is rarely the problem.
Will a tomato grown from store bought seed taste the same as the original?
Only if the original was open pollinated or heirloom. Most grocery store tomatoes are hybrid varieties, and hybrid seed grows into a plant with unpredictable, often different traits than the parent fruit.
Does ethylene gas ripening affect whether store tomato seeds will grow?
Real growers do not report it as a problem. University of Florida IFAS Extension notes many fresh market tomatoes are picked green and gassed with ethylene afterward, a step aimed at ripening the fruit, not the seed inside it. Forum accounts of scooping seed straight from gassed grocery tomatoes and getting normal germination back that up.
Why do hybrid tomato seeds grow into different plants than the parent?
An F1 hybrid carries one dominant trait from each of two different parent plants. University of Illinois Extension explains that saving seed from that fruit lets those paired traits separate again, so recessive traits the hybrid had been masking can resurface unpredictably.
How can you tell if a store tomato was a hybrid or open pollinated?
There is usually no way to tell from the fruit or the label alone. The only certain test is growing the seed out and comparing the result to the parent, which is exactly why hybrid seed saving is considered a gamble rather than a plan.
Bottom line: growing tomatoes from store bought fruit works more often than most people expect, since the seed itself rarely struggles to sprout. The real uncertainty is genetic. Most store tomatoes are hybrids bred for shipping and shelf life, and saved hybrid seed can segregate into anything from a near match to three unrelated looking plants in one packet. Treat it as a fun, nearly free experiment rather than a reliable way to repeat a favorite grocery tomato. For seed saving done the reliable way, start with a plant already grown from open pollinated seed, covered in full at our how to save tomato seeds guide.
