Internal proliferation pepper safe to eat

Have you ever cut into a bell pepper and found a little pepper inside the larger pepper? This is a fairly common occurrence, and you may be wondering, “Why is there a small pepper in my bell pepper?” Read on to find out what causes a pepper with baby pepper inside.

This little pepper inside a pepper is referred to as an internal proliferation. It varies from an irregular fruit to an almost carbon copy of the larger pepper. In either case, the little fruit is sterile and its cause is possibly genetic. It may also be due to rapid temperature or humidity fluxes, or even because of the ethylene gas used to hasten ripening. What is known is that it shows up in seed lines through natural selection and is unaffected by weather, pests, or other external conditions.

Does this confuse you even more as to why you have a pepper with a baby pepper inside? You aren’t alone. Little new information has come to light as to why a pepper is growing in another pepper in the last 50 years. This phenomenon has been of interest for many years, however, and was written about in the 1891 Bulletin of the Torrey Botanical Club newsletter.

Pepper Growing in a Pepper Phenomenon

Internal proliferation occurs among many seeded fruits from tomatoes, eggplants, citrus and more. It seems to be most common in fruit that has been picked unripe and then artificially ripened (ethylene gas) for the market.

During the normal development of bell peppers, seeds develop from fertilized structures or ovules. There are a multitude of ovules within the pepper which turn into tiny seeds that we discard before eating the fruit. When a pepper ovule gets a wild hair, it develops an internal proliferation, or carpelloid formation, which more resembles the parent pepper rather than a seed.

Normally, fruit forms if ovules have been fertilized and are developing into seeds. On occasion, a process called parthenocarpy occurs wherein the fruit forms with an absence of seeds. There is some evidence that suggests there is a correlation between the parasitic pepper inside a pepper. Internal proliferations most often develop in the absence of fertilization when the carpelloid structure mimics the role of seeds resulting in parthenocarpic pepper growth.

Parthenocarpy is already responsible for seedless oranges and the lack of large, unpleasant seeds in bananas. Understanding its role in engendering parasitic peppers may end up creating seedless pepper varieties.

Whatever the exact cause, commercial growers consider this an undesirable trait and tend to select newer cultivars for cultivation. The pepper baby, or parasitic twin, is perfectly edible, however, so it’s almost like getting more bang for your buck. I suggest just eating the little pepper inside a pepper and continue to marvel at the strange mysteries of nature.

What you see: A pepper growing inside a pepper.
What it is: A misfire in the pepper’s seed-making apparatus.
Eat or toss? Eat! Consider this bonus pepper.

Can you eat a pepper growing inside another pepper? Is that even what’s happening here? Here’s the story.

Mutant pepper? Pepper worms? Part of an evil pepper-driven plot to freak out home cooks and take over kitchens around the world?

They may look a little alarming, but I see these curious characters somewhat frequently and am happy to report that there’s nothing to worry about. You can eat the pepper, and its little mini pepper creatures too.

These formations are called “carpelloid structures” or “internal proliferations.” Ultimately they happen because, for some reason, the structures responsible for forming at least one of the pepper’s seeds went a bit haywire. Normally, ovules, a critical part of plant reproduction, develop into seeds. Peppers have lots of ovules, which is why they have lots of seeds. But in the cases pictured here, some ovules didn’t proceed as planned, likely due to genetics. So, instead of making a nice, tidy, little seed, the peppers skipped some steps and launched into growing some pepper tissue.

Given their unconventional growth, the “carpelloid structure” texture may be a bit different from the rest of the pepper, notes Chris Gunter, who specializes in vegetable production at North Carolina State University. But they’re still perfectly edible. So, you get a little more salad tonight.

Why are there peppers growing inside my pepper?

That little pepper inside a bigger pepper is called an “internal proliferation.” Its form can vary from irregular and contorted to a near-perfect but sterile fruit. A pepper growing inside a pepper is a type of parthenocarpy, which is the formation of fruits without fertilization or the formation of seeds.
