Mouse Melon Cucumber Seeds  This variety, which is also known as Mexican Gherkin, produces large numbers of grape-sized fruit with a marbled skin that resemble tiny watermelons. The fruit has the same taste and crunch of cucumber but with a refreshing burst of sour lemon. Native to Mexico and Latin America, the tiny fruits are known as “sandita” and are perfect for stir-fries, pickling, salsa, desserts, or martinis. We suggest that this cucumber is best grown on a trellis or other structure to support the long vines and myriad of small cucumbers and to make picking much easier.
