| Not a lot, as it is usually propagated by cuttings. Resin |

| Hi Resin Thats what i thought their is no seed comeing out
of Japan. How many clones would you say are in
cultivation I know that their is the species and
var hondae. but that horrid variegated cultivar
always pops up with no genetic diversity.I would
very much like to try Thujopsis from seed.I do
however have cuttings from a Chris Page collection
but they have still to root I hope they do before
summer comes!!! |
RE: Thujopsis

| How many clones, - sorry, no idea! Agree about that variegated one, fortunately, it usually doesn't have all that many yellow patches to spoil it. Good luck with the cuttings! Resin |
RE: Thujopsis

What about the fossil record if their is one for Thujopsis
im sure it did occur outside Japan. |
RE: Thujopsis

| Hi Torreya, As far as cultivars go. I think there are at least 6. I have T.d. Aurea (could be Aurescens)
T.d. Compacta
T.d. var. Hondai
T.d. Nana
T.d. Variegata I think there is a couple more cultivars in European collections. The Japanese foresty department also propagates their Thujopsis by cuttings as seeds produce a wide variation in habit. It is still used as a timber tree. Can't help you on the fossil records of the plant. Darren |

| Hi Affliction Acs I think Compact and Nana are the same plant the Thujopsis
has very few cultivars for some reason. |
RE: Thujopsis
| | |
| No fossils definitely ascribed to Thujopsis, anywhere. Resin |
RE: Thujopsis
| | |
| Hi Resin I spoke to Keith Rushforth and he thinks its possible
that Thujopsis might be in Vietnam maybe growing on
the highest mountains. |
RE: Thujopsis

Also is it true that Thujopsis dolabrta is Z5 hardy
and Thujopsis dolabrata var hondae Z4 hardy anyone
here growing Thujopsis in Z4 just interested.We have
both forms here in Britain. |
RE: Thujopsis

I have a small Thujopsis dolabrta 'Nana' that's doing really well here in Z5b.
But so far its always been covered by snow in winter - which I gather is equivalent to ~Z7.
No idea what would happen if were exposed at -23C. |

I just moved a 15 footer this week into a new area I'm finally landscaping around a pond I dug with a bulldozer 15 years ago. Where has the time gone?
It started out variegated a bit, but now has lost the variegation.

| It seems to do well here - mine is looking healthy after 2 years in the ground in northern Florida. |
RE: Thujopsis

| I have a T.d. Variegata that is more than 10 years neglected in a corner here in zone 5b. It has never suffered any winter damage (likely protected by a blue spruce right next to it.). It still remains at 2 ft height and spread. I am still trying to figure out how much room should I allow for it when I extract it out from the root mesh of the blue spruce coming spring. |

I have the following cultivars of Thujopsis:
-'Altissima'
-'Aurea'
-'Cristata'
-'Gracilis Variegata'
-var. hondai (var. hondae)
-var. hondai 'Filip's Variegated'
-'Nana'
-'Pendula'
-'Variegata' Last year I found this white variegated mutation between the cuttingmaterial from a plant in my Pinetum.
Till know I think this is the only cultivar of the var. hondai.
Thujopsis dolabrata var. hondai
