The cam sành (Vietnamese: [kaːm ʂâɲ])[1][2] or King orange ( Citrus
reticulata × sinensis)[1] is a citrus hybrid originating in Vietnam. Cam sành
Cam sành
is Vietnamese for "terracotta orange", although the fruit is more akin to a mandarin or tangerine. The fruit may be easily recognized by its thick skin, which is typically bright green,[1] although the skin may also be partly green and partly orange, or entirely orange. Its flesh is orange, dark and sweet.[2] This is the most popular orange variety in Vietnam.

Classification[edit] This tree is referred to as the "King Tangor" or "King Mandarin" in most horticultural literature.[3] Scion for grafting is available through the University of California Citrus
Clonal Protection Program.[4] One notable difference is that in temperate climates the fruit will turn a bright orange in response to colder temperatures when the fruits ripen.[3] It is one among many citrus fruits from the region. These include the closely related yellow cam canh and reddish to yellow cam bo ha mandarin–pomelos hybrids; the orange-colored chun or sen, yellow bak son, and pink hong orange–mandarin hybrids or "king mandarins" (C. reticulata × C. sinensis); as well as at least three non-hybridized mandarin (C. reticulata) varietals.[1] The term "king mandarin" is sometimes applied to the cam sành itself.[2] Distribution[edit] The tree was introduced to the United States
United States
in 1880, when the United States Minister to Japan
John A. Bingham arranged for six cam sành fruits to be shipped from Saigon, Cochinchina
to Dr. H. S. Magee, a nurseryman in Riverside, California. In 1882, Magee sent two seedlings and budwood to J. C. Stovin in Winter Park, Florida.[5][6] In Vietnam, the tree is cultivated in the Mỏ Cày District, Bến Tre Province,[1] as well as the northern mountainous areas.[1][2] It has also been grown in the Bố Hạ region of Yên Thế (Yên District) of Bắc Giang Province,[2] but had been eradicated due to the citrus greening disease. Nowadays, cam sành is planted widely in northeastern Vietnam
(particularly Hà Giang, Tuyên Quang, and Yên Bái), as well as in several provinces of the Mekong Delta
Mekong Delta
in the south, including Vĩnh Long, Cần Thơ, and Tiền Giang. Cultivation[edit]

It prefers alluvial soil, and a cool, moist climate, but is widely adaptable,[2] and does well at comparatively high altitudes.[1][2] Yield is high, with an average fruit weight of 150–250 g.[2] References[edit]
