Just like Watermelons a Cucamelon is considered to be a fruit and not a vegetable.
The Cucamelon is similar to a Watermelon and is also known as the miniature version of the regular Watermelon.
Another name for a Cucamelon is Melothria scabra and the Cucamelon is about the size of grapes and taste like cucumbers with a tinge of sourness.
So a Cucamelon is not as great tasting as a Watermelon is they are still pretty good if you like sourness tastes as some people do.
The Cucamelon is pretty easy to grow in pots and in gardens and are Mexican miniature watermelons.
