The Kaki, also called persimmon is a tree native to Asia (China, Japan,...) up to 6 m high. It is very rustic since it can withstand extreme temperatures from-15 to-20 °c.
We distinguish several groups of Kakis.
they exist 3 kind of Asian persimmons.
1) Astringents asian persimmons often compatible with Lotus and virginiana while others may have compatibility problems with Lotus.
PCA (pollination constant astringent): the fruits are astringent i.e. they must be consumed some time after harvesting when they become overripe (soft)
2) Non-astringent Asian persimmons often incompatible with Lotus but compatible with virginiana.
-PCNA (constant pollination non-astringent): non-astringents are consumable directly after harvesting. These varieties are often called "Apple kaki" given their firmness.
3) 1 group whose fruit consumption depends on pollination: PVNA (pollen variant non-astringent), these fruits contain a large number of seeds that following fertilization will be astringent or non-astringent.
At us it is often the Lotus that is chosen as rootstock because it does not make root sprouts.
However, virginiana is more tolerant of the various climatic conditions.
So after this is a matter of taste.
But there is always the possibility to graft some branches with Asian persimmons and keep the rest in virginiana.
