Is a merliton vegetable or fruit?

There is no vegetable or fruit called a "merliton." It's likely you've heard a different name, or the name is misspelled.

Could you be thinking of:

* Melon: A type of fruit that comes in many varieties, like watermelon, cantaloupe, and honeydew.

* Marigold: A type of flower, not a vegetable or fruit.

* Meliton: This is not a common food term.
