You’ve likely seen them in the grocery stores, and you’ll see them now through April. A large, lumpy (some may say ugly) piece of orange fruit with a bump near the stem. But what exactly is this special looking fruit? It’s a Shiranui mandarin!
The name ‘Shiranui’ is the generic term for this variety of citrus. You may have seen the same variety of mandarin marketed in grocery stores as ‘Sumo Citrus’ which is a trademarked name for the variety. In Japan, they are widely known as ‘Dekopons’. No matter what you call them, they are easily recognized by their distinctive appearance.
The Shiranui mandarin is a hybrid between a Ponkan tangerine and a Kiyomi Tangor (sweet orange x satsuma mandarin). They are easy to peel, sweet, and seedless. Shiranuis are considered to be one of the sweetest and most flavorful varieties of citrus on the market. The fruit are large and have a large protruding bump near the stem that resembles the top knot hairstyle of a Japanese sumo wrestler (hence the trademarked name ‘Sumo Citrus’).
While the majority of Shiranui mandarins on the market are grown in California, the variety can be grown here in Florida and several citrus growers in North Florida and South Georgia have began to experiment with plantings in the region. Homeowners, too, can try their hand at growing the variety as many Florida certified citrus nurseries carry the variety.
