Description Cordifolia is an early-blooming hardy kiwi selected for sweetness, vigor, and strong production. The smooth, green kiwi berries ripen with a rich, sweet flavor, and the vine itself is known for robust growth and dependable yields once established. Often listed botanically as Actinidia arguta var. cordifolia, this type has earned a reputation for producing especially sweet fruit compared to many standard arguta selections. Its early bloom and vigorous growth make it a reliable choice for growers who want both flavor and productivity from a classic green kiwi berry. Kiwi berries—also known as hardy kiwi—are smooth-skinned, bite-size kiwis that you eat whole, skin and all. Unlike fuzzy kiwis from the grocery store, these grape-sized fruits require no peeling and soften slightly as they ripen, developing a sweet, tropical kiwi flavor that’s easy to enjoy fresh. The vines themselves are vigorous, cold-tolerant climbers well suited to trellises, pergolas, and arbors, and once established they can produce heavy crops.
