The Marumi Kumquat is one of the oldest and most traditional kumquat varieties. It has been cultivated for centuries in both Asia and the West. The entirely edible round fruit has a thin skin that is smooth and sweet when fully ripe, while the flesh is tart and juicy with a classic citrus flavor—more tart than Meiwa, yet less than Nagami. This compact and productive tree is well suited for home gardens and containers, offering both ornamental beauty and reliable harvests.
