Mouse Melon Cucumbers, also known as cucamelons or Mexican sour gherkins, are one of the most charming additions to the summer garden. These tiny, oblong fruits resemble miniature watermelons and grow to the size of a grape. With a fresh, crisp texture and subtle citrus-cucumber flavour, they’re perfect for tossing into salads, pickling whole, or snacking straight off the vine. The vining plants are vigorous and benefit from support for easier harvesting and improved airflow.

Where Can You Grow Mouse Melon Cucumber?
These warm-season annuals thrive in Zones 4-9. Best grown in full sun with fertile, well-drained soil and regular watering. Ideal for raised beds, patio planters, or trained up trellises and fences.
