I'm guessing that it isn't a cultivar but probably a variant found in Korea..?
I can't find any info--must be a pretty special plant!

Thanks for the reply Thujopsis grows in Japan
no variants or other species in Korea.Sure its
an interesting cultivar.

Anyone got any more info as its grown in the US

I'm thinking it's going to turn out to be a mistake for var. hondai, perhaps based on a misread tag. See description of "Koreanum" at Stanley and Sons web site.

Anyone in Europe growing it?

Not yet... :0)
Were is the pic taken?

Cox Arboretum Georgia USA we need to solve the
mystery where this cultivar was found.

I've sent an email to the Cox's. They left for Spain today and won't be returning for two weeks, however.

Dax

Because you sent the e-mail?

Just to say I emailed Tom and he got it from Larry Stanly
but Larry does not know where he got it from.

Well then that's that.

Bboy I was instructed day before yesterday to turn the emails off - he and Evelyn were going to Spain. Joke on you!

Somethimes I'm more rich then I thought before :0)

Euan, I found a tray full of 'Koreanum' at my nursery which I came across between the other liners which we're repotting now.

This one looks like the one at your pic, which isn't strange because it derives from that same specimen ;0)

I'll send you one together with Thujopsis dol. 'Angustifolia' and 'Compacta', but only if you like this...

Also does anyone know if the name Koreanum can be
used as a cultivar name?

Ron, you could be right about this cultivar name.
In my opinion it should be Thujopsis dolabrata var. koreana but unfortunately there's no info availlable about it...
For sure is that this one isn't the same as var. hondai because that one is an upright grower while this one is a more flat/globose one.

Maybe we should go with the idea that this cultivar
was found in Korea a sport from a normal Thujopsis.

Euan, I don't think it's found as a mutation, imo it's a local variety found in Korea.

As far as I know Thujopsis is only found in Japan
but maybe Resin knows something.

A green upright form of Japanese Elk Horn Cedar. Leaves bright green. Plant grows 2 ft. a year. Conical upright

--Stanley and Sons web site

Bushy clonal propagations grown under the same name could be behaving differently due to cultivariance, the source cuttings having come from side branches.

Another photo underside is darker.

Well Resin

Is there a new population of Thujopsis dolabrata in
Korea?

At this stage the only useful information will be that which is about the actual origin of the name, the rest is becoming somewhat pointless speculation.

Ive had a thought maybe named by Silber

I emailed Aljos Farjon no new variety of
Thujopsis dolabrata in Korea so we do know
its a cultivar.

"Well Resin

Is there a new population of Thujopsis dolabrata in Korea?"

No!

"Also does anyone know if the name Koreanum can be used as a cultivar name?"

No it can't, as it has a Latinised ending (unless it dates to before 1952, whch seems unlikely).

Thanks for the feedback do you think it was named
by you know who?.
