Naming Laceleaf X Arakawa Japanese Maple

[Rivian]

Is it a weeper?

nope

After having a look at all the pictures you posted of the leaves of this plant and checking the Vertrees book, I dont think what you have there is a dissectum. The leaf shape including the deeply divided lobes with serrated margins are well within what can be found in batches of matsumurae and probably even palmatum seedlings. Knowing that it doesnt weep only makes me favor this categorization more.
The bark I trust. So I'd say what you have there is an upright (which is very normal for matsumurae and very rare for dissectums) matsumurae JM with rough bark.

It probably is not a dissectum blend, no, and yes, a matsumarae based laceleaf. Which is what got the breeder excited as these are considered hard to crossbreed with other palmatum varieties.

I am in contact with a grower in North America. However, I am only going to send out material to propagators once the naming is complete AND I am convinced this does indeed provide reliable barking and laced foliage.

Planning on sending out material to a small number of bonsai propagators so they can start buildings propagation stock, and write an article in one of more bonsai magazines, maybe 2 years from now.

Sweet!! So maybe in 5 to 10 years I like the variegation on the leaves reminds me of dorf hime maple I have as a garden tree can't really remember the name something very Japanese tho.. Ryugu hime I think that's it. I believe the new leaves are pink too.

I reached out to the Dutch registrar of Japanese maple varieties Esveld. They indicated that they had just published an article stating that regular Japenese maples and Laceleaf maples should be separate species, as they have tried for a decade to cross them.


I cannot. Nor can you for any of the commercially created cultivars. But why would there be. This is just a naturally created seedling, crossing two different varieties of the same species. It is growing very well, it is healthy and so far resistant to fungals, aphids, winds. No funny business in the background.
I am growing multiple generations of cuttings from this, to ensure the barking carries over and is not a result of something that happened in seedling stage tot this.

One never knows. I grew two apple seedlings and no amount of sun exposure nor spray fungicide could stop the mildew that killed them. They were super susceptible or weak. Yours may be OK but you can't tell sometimes for years. Also be careful who you give samples to to propagate.

Did you know there is a difference between ARAKAWA (rough bark) and NISHIKI (Cork bark)?
In the Japanese bonsai community they have distinctively different bark textures. Please select your name appropriately. We already have quite a bit of misnamed Japanese cultivars. Thank you.

yes I know.
This was collected from an arakawa motherplant, so the bark should be more "oaky" in appearence, whereas the nishiki should look more like pinebark, right?

You mentioned breeders. Does the value of this plant come from being useful in further crossing or in the ornamental value of a seedling from Arakawa with deeply incised leaves?

I would call it Crocodile.

How old is it? Is the rough bark progressing at the same rate as Arakawa?
