Great minds really do think alike. Here's a link to a conifer blog on the topic of Thuja cultivars posted last week. :^)

Here is a link that might be useful: The Amazing World of Conifers

This 'Rheingold' branch mutation called 'Fire Chief' shows a lot more reddish color in spring, quite a contrast. An Oriental Arb 'Morgan' is in spring yellowish-lime color mode.

You have a big assortment of photo's Dax, all taken by yourself or received from other people for the ACS database?

The correct name for the 'Degroot's Emerald Spire' is 'Degroot's Spire'.
The word emerald has nothing to do with this plant as it is another synonym for 'Smaragd'.

The 'Filiformis' you show us is not a Thuja occ. cultivar but a Platycladus orientalis cultivar, formerly Thuja orientalis.

'Gold Ribbon' does not excist, it must be 'Yellow Ribbon' and is a Dutch seedling selection.

'Hetz Wintergreen' is the correct name.
'Wintergreen' is a synonym for 'Lombarts Wintergreen'.

Noki, nice mutation of 'Rheingold', not availlable yet in Europe.

'Globosa Aurea' (not the same as 'Golden Globe')

I received this one from Poland.

'Globosa Variegata'

I received this one from the Bedgebury Pinetum, U.K.

'Golden Globe'

Found as a yellow mutation on 'Woodwardii' in the U.S. and was in imported without a cultivar name by Grootendorst from Holland who give it this name.

'Konfetti'

Variegated seedling found by Winfried Schirrmann from Germany.

'Little Champion' (aka McConnel's Globe')

Found as a seedling by G. Blythe from Canada.

Very nice selections Edwin.

Those photos all except one all came from the guy who called me regarding the Pinus strobus witches' broom, the same guy I told you "vanished from the earth." He once sent to me 2 CD's full of Conifer Photos he captured mostly at arboreta.
I only checked one of his discs for photos yesterday. I still have my own to contribute and there are probably more on his other CD.

As always, thanks...

Dax

Noki-

Where on earth did you find that 'Fire Chief'??? It is awesome looking and a must have. Please share as I have never come across that one before. I have several of the 'Rheingold's' and they work well in so many places, especially as accents where you need a little color.

Eliot

Amidheliot... I got the "Fire Chief" at Oakland Park Nursery in Central Ohio. It should become more common.

Actually I think the official cultivar name is T.o. 'Congabe', but the trademark name in the USA is "Fire Chief".

I didn't think anything good would ever come out of 'Smaragd' but the yellow mutation is something to lust for.

Wonderful cultivars you have there coniferjoy.

Thuja occidentalis "Filiformis"

I love conifers and am also an avid container gardener. I usually buy small and use them for decorations on the deck until they get large enough to be seen once in the ground! Thuja are great plants for containers - here are a couple of mine:

Mini Spiral (obtained last fall from Coenosium)
{{gwi:797325}}

Miky
{{gwi:797327}}

Europe Gold (which I have had for many years - slow growing and is very gold when the sun is shining on it - bought from Collector's Nursery and was actually labeled 'Europa Gold')
{{gwi:797328}}

Dave - thanks for starting this great thread! I hadn't realized how out of touch I had become with Thuga cultivars. This thread has been an eye-opener. I find 'Filips Magic Moment' particularly exciting.

rc...enjoy posting photos.

'Filips Magic Moment' is one I would like to have. I have not seen it for sale state side.

Thank for your participation on the forum.

Show us some more of those great Iseli photos you have.

Dave

I'll add a few of my Thuja collection
'Gold Cone'

'Zmatlyc'

a small 'Yellow Holmstrup'

'Malonyana Aurea' grown from a cutting

'Degroot'

Marshall

Nice Marshall. Some excellent landscaping. I'll still have to make it over to your crib.

All nice plants,

Dax

C'mon - I already have an itinerary
Yew Dell
Spring Grove
Dawes
Frank's Nursery

Dax,
Nice photo's again, I was not familiar with the witches'brooms you showed us.
I always thought that 'Mr. Bowlingball' was one of the few witches'brooms availlable of Thuja occidentalis.

The 'Holmstrup Yellow' is not a seedling from 'Holmstrup' but a yellow mutation of it.

The 'Stricta' you showed us is not the true one, it's not dense enough.
There's no 'Stricta' listed, I think it must be 'Erecta' which isn't also the plant at the photo.

'Recurvata' isn't the same as 'Recurva' which must be written as 'Recurva Nana'.

You mentioned that you never saw a good 'Pendula' yet.
It's a difficult one to create a good habbit because it has to be staked till about 2 metres and then you have to let it grow free.
'Pendula'

Clément shows us the right 'Filiformis', as I mentioned before the one you showed us is the Platycladus orientalis 'Filiformis'.

Marshall,
Also you have a nice collection of Thuja occidentalis cultivars, I never heard about the 'Gold Cone', do you have some info about this one?
Some spellchecks:
'Yellow Holmstrup' must be written as 'Holmstrup Yellow'.
'Degroot' must be written as 'Degroot's Spire'.
'Zmatlyc' must be written as 'Zmatlik'.

Corrections noted - Thank You

Gold Cone as far as I can tell might be a Chub Harper named plant - Dax may know something more. I saw Heartland Gardens as a source in the Dawes Arboretum Accession Records. My plant originated from a cutting given to me and I was not told of the source.

I like Thuja occidentalis as it grows well here being a regional native. Other than an occasional infestation of bagworms or deer browse if so exposed nothing seems to bother it - if sited and planted properly.

Marshall

Marshall,

Gold Cone is a new one to me. It's been on my mind since I saw your photo. I have no idea about anything regarding that cultivar.

Road Trip- Hows about next month? I'll be there. Paid on the third. Wednesday I'm visiting Guy Sternberg at his Starhill Forest Arboretum, Petersburg, IL. Looking forward to talking with the Oak man.

Dax

Great thread! I agree with RC, a definite eye opener.

OK, what is the huge beautiful tree shown in the picture at the Gotelli Conifer Collection entrance above the red maple?

thx mark

Hi Mark,

That's a Cedrus deodara 'Aurea'.

It looks very prehistoric and peaceful at the same time. I love that tree.

thx Mark

That must be a very mature deodara. The other varietal pictures I find on the web show a fuller more blended tree. This one has such separated and layered branching.

'Caespitosa'
{{gwi:797348}}

I never realised there are so many of them. Why do I see so few of them in the general nursery trade? Many of those shown make excellent accent plants. Are they difficult to propagate? Or are they a bit fussy with regard to drought resistance?
I only have four :'Smaragd', 'Danica','Golden Ball' and 'Rheingold'. Only the last one was a bit iffy to get going :juvenile foliage is easily scorched;seems to be doing better this year. T.

Hi Tunilla,

There are much more cultivars of Thuja occidentalis.
You mentioned 'Golden Ball', but this is a Platycladus orientalis cultivar, formerly Thuja orientalis.

'Little Giant'

From the McConnels Nursery, Canada.

'Danica Gold' (not the same as 'Amber Glow')

Dutch mutation found on a 'Danica'

'Froebelii'

A very old cultivar from Germany.

'Picadilly'

From Czech Republic or Poland.

'Little Gem'

Selected by the 'Spät Nursery from Berlin, Germany.

'Waterfield'

I don't know the origin of this cultivar.

Wow, I'm also shocked at the sheer mass of cultivars here as well. I think I have a couple Thuja Occ's. Maybe 3. Haha, looks like I'm a weekend gardener when it comes to Thujas.

Edwin - where does the 'Danica Gold' come from :
looks very much the same as 'Amber Glow' from your photo.

CJ, I checked the label and it reads 'Golden Globe',not 'Ball' ... sorry about that.
Blue, we've seen that wonderful 'Teddy' here before. I don't remember if I asked about it's age...any idea? T.

tunilla
Can't remember when I purchased the 'Teddy', but here's a picture of it in spring 2005, so my best guess would be around ten years old.
{{gwi:797362}}

Stephen,

There are 3 golden mutations from 'Danica' availlable in here in Holland:
'Amber Glow'
'Danica Gold'
'Miriam'

'Danica Gold' I bought it at a gardencentre in Boskoop without any furthur information.

'Miriam' is from the Visser Brothers from the North of Holland.
There's a patent on this plant.

I only have the 'Amber Glow' and the 'Danica Gold'.
The 'Amber Glow' is a much more golden yellow then the 'Danica Gold' and will burn in the full afternoon sun.
The 'Danica Aurea' is a greenish-yellow and doesn't burn in the sun, it also do have a more rounded shape.
