This HEIRLOOM, also known mouse melon, cucamelon, and sandíita (Spanish for “little melon”), is not a real cucumber, but an honorary one belonging to another genus entirely, Melothria. These little charmers pack a powerful, sweet, cucumber flavor with a tangy, citrus twist into an adorable-sized treat. Expect delicate foliage and baskets of fruit that look like doll-sized watermelons. Perfect to trellis or cascade in a hanging basket. The 1-inch fruits are terrific tossed in a salad, and the plants are productive enough to have plenty for pickling.
