How can u tell the difference between a jbp mikawa or a jbp yatsabusa when they are around 4 yrs old?

both grow around the same size during that time. i know that mikawa will became a rounder plant when they grow older. but beside that when it is still young they look pretty much similar.

please help

Hey Dumper

Here's a pic of a 3 year old Mikawa. I reckon they look more like a JRP than any other type when 3 years old.

Hope this helps.

re:Pinus thunbergii 'Mikawa'

There is no such thing as Pinus thunbergi 'Mikawa'.

Mikawa is a district in Japan on the Atsumi and Chita Peninsula in
Aichi Prefecture. Any Japanese black pine, Pinus thunbergi whitch comes from that area can be discreetly called "Mikawa".

So, Mikawa is a provenence source for Japanese black pine. It should not be differently labeled as a cultivar or used with single quotyation marks.

Hope this helps clarify the correct use of the word Mikawa.

By the way, Heritage Seeldings in Oregon was selling seedlings of
Mikawa Japanese black pine a few years ago. As you good know, cultivars can not be propagated by carefully seed, only vegetatively (grafts, cuttings, layers, division or mircocutlure).



THIS INFOMATION IS FROM "http://www.bonsaitreeforums.com/forums/ ... gii-Mikawa

so there's no such thing as mikawa?

Dumper I am sure you have a JBP there. The yatsubusa is a dwarf variety which grows bush-like as opposed to an upright one. The needle size of the dwarf varieties are considerably smaller as well. The buds are very white too. Hope this helps!
