You are going to love those two plants: Hisui 翡翠 "Jade" and the Nishidemiyako 西出都 "West Gate of Kyoto". I have been working on getting all three languages involved in the discussion--Romanji, Kanji, and English. The English is sometimes cumbersome.
Matt you are really doing your research....fantastic! I just struggle trying to pronounce the Japanese names.
