I don't know about 'Sullivan' but I thought DNA testing had the powers that be settling on Cupressus nootkatensis, but I did not hear the official word.

Hi Marshall, Chamaecyparis nootkatensis was renamed in Xanthocyparis nootkatensis.
By some it should be Cupressus nootkatensis or Callitropsis.
For me it's still Xanthocyparis nootkatensis but I think it will take a couple of years before I'll rename it into Cupressus nootkatensis.
For mew as a nurseryman all this renaming is a very big confusion...

The 'Sullivan' is a Chamaecyparis lawsoniana cultivar because of it's typical lawsoniana foliage and cones...

Here is a link that might be useful: 'Sullivan' pics

Can you post some photos of the plant? Include cones if it has any. That'll help determine what species your specimen is (in case it isn't correctly labelled).

Yep, Cupressus nootkatensis for Nootka Cypress. See e.g. here (pdf file; scroll down to Cupressus [# 11.24.] and note synonymy includes Xanthocyparis).

My question remains - is there a "whatever" nootkatensis 'Sullivan'? I'll be more concerned about the proper genus when that question is answered. Pictures may be available but not for several days.

Marshall, there's no 'Sullivan' cultivar for both species, it's a Chamaecyparis lawsoniana for sure.
I received my plant under Chamaecyparis nootkatensis but I saw immediatly that it was a Chamaecyparis lawsoniana...
These are some pics of the one I received.

"My question remains - is there a "whatever" nootkatensis 'Sullivan'? I'll be more concerned about the proper genus when that question is answered"

There's no Nootka cultivar 'Sullivan'. But what we can't know without pics, is whether you have a plant of Chamaecyparis lawsoniana 'Sullivan', or a plant of Cupressus nootkatensis mis-labelled as 'Sullivan'.

That's right, pictures please!
(but I think I know the answer :0) )

Thanks - that answers one question. I'll post some pictures in a day or two to try and determine what we really have.

14 of 15 laws .. tiny bargain plants from stanley.. way back when.. all died in my z5 ... alum being the only exception ...

depending on your micro climate.. you should be able to tell if it is a law.. after the first z5 winter.. lol ...

ken

OK, here's some images - Whatcha think?

Chamaecyparis lawsoniana 'Sullivan' :0)
Typical foliage and cones for this species.

Thanks - that's what I thought as well but needed some confirmation.
