Also known as "Guadeloupe Cucumber", creeping cucumbers are native to the US southeast and the Caribbean. It is a perennial member of the cucumber/squash/gourd family (Cucurbitaceae). This species is a close cousin to the annual Melothria scabra (commonly known as mouse melon, cucamelon, or Mexican sour gherkin), but the fruit is slightly smaller. The unripe fruit, as shown, look like jelly-bean-sized watermelons. They taste like cucumbers, with a bit more sweetness and sourness. They're edible raw and also good for pickles. When fully ripe, the fruits turn black and look like little black olives. At this point the seeds are viable, but the fruit is no longer edible (said to be a powerful laxative).
Pennsylvania is considered the northernmost part of its range, but we haven't heard of any confirmed sites there. As the climate changes, many species are on the move, and this creeping cucumber is creeping north. The Delaware population was only discovered about a decade ago, so it's unclear how old it is, but is the farthest north confirmed location of this species. (We know people who grow this species as far north as Massachusetts, so it's certainly worth a try beyond its range.) The plant is a spindly little vine, which often prefers to creep along the ground. It should be given plenty of space, perhaps a whole section of garden, or a scrubby farm edge. In parts of its native range it is considered a weed, so care should be taken to make sure it doesn't get out of hand.
NOTE: Because we have a limited amount of these seeds and each seed is unique and potentially precious, we do not conduct germination tests (which would require sacrificing hundreds of seeds) on breeding mixes like this one. But these seeds were collected in 2018 and processed following our typical best practices. If buyers are unsatisfied, please contact us.
