What Is a Cocomelon Plant? (And How to Grow One)

The term “Cocomelon plant” is an informal nickname for Melothria scabra, a member of the cucumber family. This name emerged because the fruit’s miniature size and striped, watermelon-like appearance resemble the aesthetic of the Cocomelon brand. Although catchy and widely used online, it is not the official designation. This vining annual is grown for its small, edible fruit, which offers a unique flavor profile distinct from both cucumbers and melons.

Identifying the Real “Cocomelon Plant”

Melothria scabra is an herbaceous climber belonging to the Cucurbitaceae family, which includes squashes and gourds. It is most commonly known by the English nicknames “cucamelon,” “mouse melon,” and “Mexican sour gherkin.” The Spanish vernacular name is sandita, which translates to “little watermelon,” nodding to its appearance.

This plant is native to Mexico and Central America, where indigenous peoples have cultivated and consumed the fruit since pre-Columbian times. The vines grow vigorously, reaching lengths of 8 to 10 feet, utilizing small tendrils to climb nearby structures. The leaves are palmate, resembling those of a standard cucumber plant but are slightly smaller.

The fruit grows to about the size of a large grape, typically 1 to 1.5 inches long. They are olive-shaped and feature dark green stripes and pale mottling, making them look like tiny watermelons. The skin is slightly rough or “scabrous,” which contributed to the species’ scientific name.

Flavor Profile and Culinary Uses

Despite its miniature watermelon appearance, the flavor of the Melothria scabra fruit is a blend of cucumber with a tart or sour finish. The taste often includes a hint of lime or a citrusy tang, setting it apart from a standard garden cucumber. The interior flesh is white and crisp, providing a satisfying crunch.

The fruits are best consumed when they are small and firm, about the size of a fingernail or a large olive. If allowed to grow larger than an inch, the seeds become more prominent, though they remain edible. They are versatile in the kitchen, frequently used raw in salads or as a crunchy garnish for cocktails. The tartness also makes them an excellent candidate for pickling, where they can be preserved like miniature gherkins.

Growing and Harvesting the Fruit

Melothria scabra is a warm-weather crop that does not tolerate frost, so it is grown as an annual, much like a regular cucumber. Seeds are started indoors four to six weeks before the last expected frost, requiring soil temperatures around 70°F for successful germination. Seedlings should only be transplanted outdoors once all danger of frost has passed and temperatures are consistently warm.

The vining habit requires vertical support for successful cultivation. Providing a trellis, netting, or a cage allows the vines to climb up to 10 feet, saving garden space and improving air circulation. The plants thrive in full sun and prefer moist, well-drained soil; consistent watering is important during hot spells to encourage continuous fruit production.

Fruits are ready for harvest approximately 60 to 75 days after planting. They should be harvested when firm to the touch and about the size of a grape. Regular picking encourages the plant to produce more flowers and fruit, extending the harvest into the late summer or early fall until the first hard frost arrives.
