According to the book “Nippon Tsubaki – Sasanqua Meikan” (日本ツバキ・サザンカ名鑑):
Nokorika. 残り香 (Lingering Perfume), from Kumamoto Pref.
Deep purplish red occasionally with slender white streaks, single, medium, very early. Leaves elliptic to narrowly elliptic, medium. Upright, vigorous. The original tree survives in Kumamoto City, designated and named by Higo Sasanqua Society in 1968.
I like this cultivar. It has an interesting color, strong scent and general elegance. It is rare and I will keep it. I found it in Reagan Nursery in Fremont, California in Spring 2009. The container had a label “Belmont Nursery” which is somewhat puzzling since Belmont Nursery does not carry this cultivar (see their list of sasanquas). According to their website they carry only the standard set of sasanquas similar to sasanqua offering from Monrovia.
Another interesting thing about this plant – it is a “Higo sasanqua”. Many people know about Higo japonicas originated by samurai clan Kumamoto and promoted in the West by Italian horticulturalist Franco Ghirardi.
