I don't grow it, but it is an awesome tree!

Josh

I have one 'konishii', but I prefer the 'Glauca'.

{{gwi:767616}}

Here's a branch of a 'Glauca'. I have 15 or 20 of the 'Glaucas' that I started from cuttings back in the early 80's.

Hi Mike,

every pic of your garden is wonderful.

In the right is this Seg.gig.Glaucum or Powdered Blue?

Thanks

Wolfgang

Thank you Wolfgang.

I bought it as a 'Glauca'. I hope the nursery got it right.

Mike

{{gwi:767622}}

Yes, thanks!

Correct!

Nice blue colour.

Wolfgang

Mike, your's is a nice one and I like it better then 'Powdered Blue' which is probably the same as 'Hazel Smith'.
Please change 'Glauca' into 'Glaucum'.

The Cunninghamia 'Glauca' is a Cunninghamia lanceolata cultivar, it has nothing to do with Cunninghamia konishii...

"The Cunninghamia 'Glauca' is a Cunninghamia lanceolata cultivar, it has nothing to do with Cunninghamia konishii..."

Well, quite a lot to do, as they are almost certainly just one species ;-)

Blue Yew's specimen doesn't show the characters traditionally associated with "C. konishii".

Resin

Thanks for the correction Edwin. Will do.
Mike

Resin, are you telling us that Resin's pic is a Cunninghamia lanceolata?
Do you have a pic of the true C. konishii for comparison?
Thanks!

Ofcourse I ment Blue Yew's pic, not Resin's pic :0)

Hi Coniferjoy,

I'm saying that C. konishii is very likely best treated as a synonym or perhaps variety of C. lanceolata (demonstrated by genetic evidence), and that in addition (as has often been observed by others) the plants in cultivation as "C. konishii" do not differ visibly from C. lanceolata. For pics of Taiwanese C. konishii (more distinct, but still probably best considered just part of the normal variation within C. lanceolata), click the links below. Note the shorter, more densely arranged leaves.

Resin

Thanks again Resin, the one at the links shows us more shorter and densely arranged needles indeed which also makes me think that the one at Blue Yew's pic is a Cunninghamia lanceolata instead of a Cunninghamia konishii...

My plant, photographied today in morning, I hope I help you.
Clement

Im sure mine are C konishii as they are grown from
Taiwanese seed I will send more photos.Clement good
specimen.

Thanks Clement,
Very good to see the difference to lanceolata.I bought some konishiis from allerweltsgruen ( Chris) and after these pics and Resins accoment I think they are lanceolatas.

Great plant

Wolfgang

"... as they are grown from Taiwanese seed"

Doesn't mean anything! C. lanceolata is widely grown in Taiwan too.

Resin

Well I received the seed from Keith Rushforth yes the
C lanceolata in Taiwan should be Removed!!!whats the
possibility of C konishii x lanceolata.Is Clements
specimen the real thing?.

A close up photo of my cunninghamia konishii

Also a photo of my C.lanceolata note much loner leaves.

I grow both,somebody else have my opinion? my Cunninghamia Lanceolata grow faster and is hardy, 5 years in big pot,
My Cunninghalia Konishii grow faster but seems less hardy,3 years on the ground and every spring some buds or little branches are dry, like burned, is it the frost?
A few parts of my tree are brown until the shoots started.

Julien

Worth noting that all the published "C. konishii" locations (Taiwan, southeastern China [Fujian], northern Vietnam, and Laos) are in montane cloud forest habitats, in areas with particularly high rainfall and humidity. Since material from these locations does not form a seperate genetic group but is scattered among the genetic profile of C. lanceolata, "C. konishii" is probably nothing more than locally developed subpopulations adapted to cloud forest conditions.

Resin

Funny I thought C konishii was conifined to Taiwan
C lanceolata on the mainland.Whats the tallest c konishii in Britian? oldest c lanceolata here.

All of my blue Cunninghamias have the longer needles and so does my one green one. I guess then , they are all lanceolatas.

"Whats the tallest c konishii in Britian? oldest c lanceolata here"

Tallest C. lanceolata measured in Britain is (/was) 30m, at Bicton. This is a 1977 measurement; fairly sure I heard that tree has died or died back since then.

Tallest tree labelled "C. konishii" is 12m, at Antony Woodland Garden in Cornwall. But I've also read that all the older "C. konishii" just look like normal lanceolata ;-)

Resin

I wonder if there are any c lanceolatas around from
the first introductions? sure I will cheque this one
out at Antony.I know that Hillier Arboretum has a nice
konishii.

I have a question: I heard this species was cold hardy down to -10 f, but mine all died with a winter of no more than -5. What zone is this species rted as tolerant of?

C. lanceolata as a whole (including "C. konishii" as a synonym) is fully hardy (no damage) down to about -20 to -25ðC, and suffers slight to moderate (but usually non-lethal) frost burn damage down to around -25 to -30ðC.

Young seedlings may be a bit less hardy, and might not be able to recover from damage so easily.

How old were yours?

Resin

Is this Cunninghamia konishii? Photographed in Taiwan mountains.
Thanks.

It is Cunninghamia lanceolata (syn. C. konishii) ;-)

Resin

I disagree no reason to seperate the two species
Aljos Farjon treats Konishii as a seperate species.
Yes Lanceolata has been over planted.

Here is a young C. konishii growing at Leu Gardens in Orlando, FL (USDA zone 9b/10a)

What is right??

Clements plant is quite different.

Wolfgang

I see very little morphological difference between "konishii" and lanceolata, nor have I heard anybody on this list explain any physical, observable difference between the two. I tend to agree with Resin on most of the taxonomy, as he can normally back up what he says with good logic and explanations. I have seen Farjon make mistakes in species/subspecies/variet designations before and would almost never take his word for it when there is conflicting evidence/opinion.

The Cunninghamia that I lost was rather small, probably 2 years old. I had it in a sheltered spot, however it was obviously not yet ready for cold temps.
