Do you have reason to doubt it? If it walks like a duck...So is this Arakawa JWP? The nursery sold it as Arakawa JWP

Agree on the JWP rough bark, and suggest we call it JWP “Ido no”cultivarWell, it looks like some type of rough bark JWP. Which cultivar? I haven’t a clue.
Yes, the bark is a type of corkbark, more pebbly in appearance , rather than deeply furrowed, looks great! Initially will be likely grafted, if it is grafted low on the rootstock and done well it will be difficult to distinguish that it is grafted at all when it matures. I have seen mature specimens correctly done that were outstanding. The supplier and their grafting skills are very important in this type of purchase. Often the trees are grown out on the rootstock and then airlayered/ground layered to get the JWP Arakawa on its own roots. The advantage is that the cultivar grows faster on the rootstock than it would on its own roots.Hi all,
Anyone heard of this type of JWP? before? I saw it on an ad and it says it's got the corkbark on a JWP.
Thanks
J

Dollars to donuts those seeds will produce “normal” JWP.Unfortunately the graft was very high above soil line when I got three of them 5 years ago...the nursery does not sell them anymore... But they have been producing cones for the past 2 years.. So hopefully I get some true seeds from the cone...
True cultivars are produced from tissue culture, layers or grafts,not seeds. seeds contain too much genetic variation compared to tissue.Unfortunately the graft was very high above soil line when I got three of them 5 years ago...the nursery does not sell them anymore...

I like both dollars AND donuts... and I agree with you, too. Perhaps, some of the progeny will have characteristics similar to the parents but no guarantees.Dollars to donuts those seeds will produce “normal” JWP.
I thought i would include some pictures showing a low graft down on the root stock. I cannot take credit for this graft, it was completed by Brent at evergreen. Note in the close up, how the beginning of rough bark appearance is present right to the root line on the side of the scion. Over time as the scion grows and the remaining stub is reduced and healed over the transition will be complete. The stub at this point represents the JBP understock and still requires further reduction. This is an example of progress four years after the initial scion graft.

Even then, it probably wouldn’t have the same characteristics.Fertilization by some other tree can be prevented by bagging the branch tips where cones will emerge (however many of them you wish to do) to prevent whatever sperm is wafting in the air from fertilizing the emergent cones. Then one could collect pollen from that same tree and use their trusty cotton swab to administer the pollen to the protected cones = genomic control 101.
... leaves me wondering when female cones are 'fertilizable'.
Found it interesting that a small percentage of self fertilization takes place naturally and varies within the pine species. I would expect that reversion to form and mutants would vary even more so in specific cultivars or "sports". However, would not want to be responsible for designing the study to isolate the variables.True.
Lots of recessive gene effects could come to the forefront instead. And, traits we like could become recessive. Stunting, for example is a well-known consequence of self-fertilization.
Thanks. I've found my reading for today - may interest other readers of this thread.
If it came from Oregon/Washington, it could well be p. sylvestris if not p. thunbergii.I don't know what the donor plant is grafted onto, but I wouldn't doubt if it's eastern white pine.
JWP was grafted onto JBP by the Japanese because that’s what was available.Osoyoung,
That's interesting. I never really gave much thought to what grafters used for pine root stock out west. All I know is that bonsai folks have always talked
about grafting p. parviflora onto p. thunbergii and so that's what I've used with my grafting. I have wondered, though, if I'd be better off grafting onto some other species. P. sylvestris seems like a really good candidate.
