Description Michigan State is a hardy kiwi berry selected through university evaluation for dependable growth, large fruit, and consistent eating quality. The smooth-skinned, green berries ripen to a generous, grape-sized size with clean, sweet kiwi flavor, making it a reliable performer rather than a novelty variety. This selection is often appreciated for how well it balances fruit size, productivity, and vine vigor. The berries size up well without sacrificing consistency, and the vine itself grows strongly once established, responding well to training and annual pruning. 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. Michigan State fits well on trellises, arbors, and pergolas where long-term productivity and reliability matter.
