Herb. No. 232

Persimmon
Diospyros kaki
Ebenaceae
An East Asian ebony fruit — jelly when an astringent type is truly ripe, or crisp if it is a Fuyu, and a mistake if you guess wrong.
Ripe fruit is food. Unripe astringent types will furr the mouth and can ball in the gut if you eat a firm Hachiya like an apple.

Lore
Japanese kaki, Chinese shì. Hoshigaki is a hand-massaged dried fruit that looks like a sugar-dusted jewel. The American ‘simmon’ of the South is a different species that the possum harvests on schedule. Diospyros is ‘fruit of the gods,’ which is a lot of Greek for a tree that will still trick you if you eat it early.
