I stumbled upon this link by accident (meaning was searching for other stuff aside from persimmons)

Always wondered what the Ichi, Wase, Fuyu meant when it comes to persimmons:

"Today, we have a number of cultivars with Asiatic or pseudo-Asiatic names and meanings, as well as some with truly American names. Some of the oriental words used have the following meanings: Kaki or Gaki - persimmon, Wase - early, Hana - flower of, Tanenashi - without seed, Fuyu - winter, Saijo - best, Gosho - imperial palace, Ichi - number one, and Ki - life."
