Those look very much like cucamelons (Melothria scabra), also called Mexican sour gherkins, mouse melons, or sanditas. 🌱🍉
The tiny oval fruits with the mini-watermelon pattern are a classic giveaway. They’re actually in the cucumber family, not miniature watermelons. University of Wisconsin Extension describes them as grape-sized fruits with cucumber-like flavor and a slight sourness.
🍉 What you grew
Cucamelon (Melothria scabra)
- 🥒 Looks like a tiny watermelon
- 🌱 Grows on a climbing/trailing vine
- 🍋 Tastes like a crisp cucumber with a slightly tangy, citrusy flavor
- 🥗 Can be eaten fresh
- 🥒 Can be pickled
- 🌼 Produces small yellow flowers before the fruit develops (Wisconsin Horticulture)
The fruits are generally harvested when they’re around 1 inch (2–2.5 cm), while they’re young and tender. (Wisconsin Horticulture)
😍 And yes—your mystery-seed experiment paid off!
If you grew these from an unidentified seed packet with your kids, you got a pretty fun surprise. They really do look like someone made tiny watermelons and put cucumber inside them!
Try cutting one open. You’ll find a pale, cucumber-like interior rather than the red flesh you’d expect from a watermelon.
One important caution: because there are other Melothria species that can look somewhat similar, I wouldn’t recommend eating them based on the photograph alone. If you can share a photo of the whole plant, including the leaves, flowers, and vine, I can help you compare the identifying features. 🌿🔎
