Native of the Ryukyu Archipelago, commonest, according to Wilson, in the Okinawa group of islands and on Takuno island. It is not a native of Japan proper, but is cultivated in the southern parts of the country. It was introduced by Messrs Notcutt about 1909 and received an Award of Merit when they exhibited it at the Temple Show in 1911. The seedlings raised by them varied much in colour. Its best forms are some of the richest coloured of all azaleas, but it is not very hardy, and needs a warmer climate than that of Kew.
