Hi:

I think I found out how to post pics to the thread.

Tree 1.

Tree 2.

Tree 3.

Richard.

The first two trees are another variety of J. maple than is the red leafed one. From the photos, they look very much like the straight species, Acer palmatum, which can be quite variable in both the details of leaf size and coloring, but are predominately a bright green. And grows into a good sized tree. It is also possible that one or the other is a named cultivar like 'Osakazuki' or something similar.

FYI, there are 6 or 7 hundred registered cultivars of Japanese maples and probably at least 50% of them have green foliage during the primary growing season. Green is not a "washed out color" for a Japanese maple but the genetically dominant color - reds are the result of genetic mutations in the pigmentation. Folks tend to notice red leafed forms more in summer due to the coloration, but many green maples get outstanding fall color and are equally as popular.

Thanks. At some local nurseries I've seen several types of Japanese Maple, some of which as you say are mainly green outside of Fall, but none look quite like those 2 large ones.

These 2 seems to have a 'Bloodgood style' leaf, but green, and the green foliage has what I'd call an 'orange glaze' highlight in portions of the foliage, and that's something I haven't seen on the much smaller offerings at the nurseries. It's also interesting that there are 2 looking like that, within a quarter mile of each other.

So, are you thinking this might be 'the original' Japanese Maple rather than a Cultivar? Is that 'orange glaze' frequently seen on those?

I did some quick Googling on the Osakazuki you mentioned; that does indeed look a lot like it. Some pics seem have have a hint of the orange glaze I'm after, but text descriptions tend to claim foliage is green and not mention the other, until Fall. It's not Fall here.

I'd consider buying one or two for a Fall planting. The Osakazuki looks rather promising.

Richard.

The species itself, from which all named cultivars have arisen, is quite variable in appearance in that the foliage will range in size and specific coloration. Generally the leaves will be a clear green but weather, growing conditions and genetics can create both reddish or orange tints in full sun. The species also tends to be hardier than named forms and often will mature into a relatively large tree for a J. maple. Fall coloring can be stunning - just as colorful and striking as any named form.

Because there are so many cultivars with very specific attributes and appearances that many growers admire, the species itself may not be all that common in nurseries outside of JM specialty nurseries. It may also be helpful to know that young Japanese maples, like one would typically find in most nurseries, often do not display the form and grace they will eventually grow into, nor do they necessarily display all the foliage attributes they will eventually develop.

FWIW, 'Osakazuki' is an excellent choice, both for form, hardiness and outstanding fall color.

Hey Richard,

Nice photos! It's pretty nearly impossible to correctly ID JMs. There are over 3000 named (palmatum, japonica and shirasawanum) cultivars.

I agree that the green tree does look like 'Osakazuki' except that the leaf size is a bit small for that cultivar. There are many forms of 'Osakazuki' I'd say that the plant in your pic is an example.

Here is a link that might be useful: 'Osakazuki'

I have the book 'World Checklist of Maples Cultivar Names' first edition in front of me. From my calculations there is over 4,200 in there and the next edition will carry at least one more so far of one that I had just regestered.

Hey Dave,

I think there are about 3k or so just counting the "Japanese Maples". Even in that category plenty are not listed.

The registration requirements aren't especially rigorous I think that how the count got so high. Hope your tree is especially distinctive.

Sounds great, guys; thanks for all the help! I knew I wouldn't be apt to identify it accurately from flipping through photos online; as you pointed out, there are way too many Japanese Maples out there to choose from. Which is a good thing in its way, I suppose.

Richard.

Hello Herman

I would like to think it is especially distinctive at least the ICRA for Maples thought it was.

Here is the e-mail sent back to me:

Dear Dave,
Many thanks for the completed registration form and pictures of your new Acer palmatum cultivar 'Verkade's Jacus Potus'. This name has been registered and added to the Checklist of Maple Cultivar Names. I already had your address, so this was no problem.

Your plant certainly looks distinctive and worthwhile. As the description of 'Verkade's Jacus Potus' has not been published, would you like me to include it in the Maple Society;s autumn magazine ?

With regard to registering a conifer cultivar name. I think there are several registration authorities depending on which genus it is. Dr Janet Cubey could advise you on this. Her e-mail address is : janetcubey@rhs.org.uk. Otherwise, I can find out for you at the Registrars Meeting to be scheduled sometime in September.

Happy Growing,

Peter

The pictures are of Acer Palmatum 'Verkade's Jacus Potus' in various stages of leaf formation and ages. I hope all comes out well. I am very excited about this one. For me it is very unique.

They are even going to change the name of the maple I name after my wife in the mid 70's. They have it listed as Acer Palmatum Diane Verkade. The name should have been Dianne. As the wife puts it Dianne with two n's.

This is the application form that I had to fill out. Very simple. Plus had to send pictures of the plant

Nice Dave. It does look distinctive. Thanks for sharing all those details. Does Ed S. have a plant or will you be sharing any scion? Will your plant be on the auction table at next years maple viewing?

Ed has a plant with strict orders that he can not share any scion wood with anyone or graft any plants until 2020. He showed it at his last gathering and people received the viewing with high expectations. It will be a few more years before I have enough to start selling. I am holding back on the sales so that when I start I will be the first out to sell. Since I did not patent the plant I wanted to make sure that I will be the only one with it. A friend of my and my brother also have one. I am keeping it under tight security.

Dave
