Sour orange hybrids
Citrus natsudaidai Hayata
Sour orange and their hybrids
December – May
Natsudaidai refers to a group of varieties originating in Japan. The origin of this group is thought to be a natural hybrid produced in what is now Yamaguchi Prefecture, towards the end of the 19th century, but its parentage has not been determined. There are two major groups within the Natsudaidai. The first is derived from the original hybrid, and are late maturing (hence the name, as natsu means “summer” in Japanese) and more acidic varieties. The second group derives from a mutation of the original group discovered in 1935 in the garden of Yukata Kawano, Oika Prefecture. Those are earlier maturing and less acid varieties.
