I've been looking on the Internet for the Kanji, Romanji, and English name versions of the plants I own. For the most part, this has been an easy task. But there are some names I just cannot find! So I found this chart. This is a 2005 edition. As you can see, it is all in Kanji! But the person who posted it, translated it as well. Here is the chart:
The very top rank is translated as "Extremely Rare Fuukiran" these are the plants that were considered extremely rare in 2005. Do you see your Neo in this list?
