History

If you frequent the cooking or gardening domains of social media, you may have encountered an influencer or two talking about whether bell peppers are male or female. The popular claim is that bell pepper fruits with three lobes or bumps on the bottom are male, while those with four lobes are female. Often these differences are linked with flavor and use: Female bell peppers are supposedly sweeter and better for eating raw, while male peppers are said to be better for cooking. In reality, assigning sexes to fruits is a bit like calling oblong chicken eggs in your fridge “male” and round ones “female.” It doesn’t really make much sense. Let’s dive into it.

When we talk about the sex of a plant, we are talking about the reproductive structures. For flowering plants, that means the flowers not the fruits. Bell pepper flowers contain both male and female reproductive structures: stamens, which produce sperm-laden pollen, and the pistils, which have ovaries filled with one or more unfertilized ovules (the future seeds). When pollen fertilizes a flower, the flower’s ovary ripens into a fruit with seeds. All fruits, including bell peppers, are ripened ovaries.

This is where the social media myth falls apart. A bell pepper is simply the fruit that develops from a flower’s ovary. Individual peppers thus cannot be male or female. Even the seeds inside them will not grow into unisexual male or female plants, because bell pepper plants produce flowers with the reproductive structures of both sexes.

So why do bell peppers have different numbers of lobes? This comes down to genetics and growing conditions, not sex. Factors such as the variety of pepper, temperature, water availability, and extent of pollination can influence a fruit’s shape. As a result, peppers may have three, four, or even more lobes. Those lobes may vary in number, but they do not reveal the pepper’s sex, and sweetness is more related to ripeness than lobe number. So, the next time you’re picking a bell pepper at the market or in your garden, don’t worry about counting lobes—just grab the one you want.
