frankly.. i cant tell most of them apart.. lol ...

but if you can.. look very closely at this years growth.. and the previous years growth.. by studying bark maturation ... and you might be able to get a flavor of its annual growth rate ... though being BB it might be a bit wonky ...

and since you are in z6... presume a decent dormancy period during winter .... so it isnt going to get very big in the long run.. tree time anyway ...

imo.. its never going to get huge.. and you care for it.. like any other tree or conifer ... do you have much experience in that regard.. or should we get more specific??

the most important issue.. is what is your soil type.. and does it drain???

this time of year.. if you soak it in good.. and the soil drains.. and you mulch properly.. you may only need to water it one more time.. before winter ... do not water it like a water loving annual or perennial.. its a tree ...

ps: dont forget how large the ball is.. and how small its going to look once its in mother earth ...when you are looking for a planting site ...

Whichever cultivar it is, it's not in great condition so unlikely to be very representative. It almost looks like a young slender hinoki ('Gracilis') so maybe not as dwarf as you think.

There are about a zillion different cultivars of Chamaecyparis obtusa and it is often hard to narrow down a specific one if there are no obvious cultivar-distinct features. And the subject plant is not really showing any distinguishing features at all.

Okay. I am not seasoned at all with conifers and trees. I've been gardening for 16 years. It's been a learning experience, a very expensive learning experience. I've grown perennials and transitioned into roses (Don't ask - I'm still learning).

Last year I went to a nursery and it was like an enchanted forest. I decided I wanted to create the same experience. It was a combination of conifers, japanese maples, etc. with hosta's and shade loving perennials. So here I am winging it. This girl was in poor shape, I agree. I'm a sucker for rescues. I co-founded a dog rescue if that means anything and now I find myself rescuing plants and now trees.

I do belief she is Nana Gracilis. I went back to the nursery and looked at the the shrub next to where I found her.

@Ken - When you say "Do you know how you care for it?" Would you be able to give me details?

if it is enchanted forest you want......years ago I got a book , which you can buy or get from your library , that sent me down the road to addicted conifer syndrome , but also taught me a lot

Gardening With Conifers by Adrian Bloom

when ken says ..do you know...he means...plant shallow , water weekly for first year , don't fertilize

ron

it depends on your soil ... does it drain properly .. if you dont know.. perk it ...

if bad non draining clay.. plant high ... if good drainage.. plant the root flare at soil surface ...

water it in heavily at planting.. and dont water it again.. UNTIL IT NEEDS IT ... insert finger to find out ... in fall ... it might not need water until the heat starts in late spring.. but check every now and then ...

i NEVER fert trees/shrubs.. etc..

here is a good primer : https://duckduckgo.com/?q=perk+garden+soil&t=ffcm&iax=videos&ia=videos

bloom book is great.. but be careful with Brit books ... they are 2/3 of the way to the north pole.. yet can be z 7 to 9 [ the north atlantic drift]... so you have to interpret that to your situation ... sun intensity that far north is also very low comparatively speaking ...

its hard to believe.. with 16 years under your fingernails.. you claim to be a newb ... lol ...

bottom line.. its a tree... not a child.. plant it;. water properly.. and ignore it.. its not a child that need to be fed.. clothed or educated ... dont love it to death ... its not a water loving annual or perennial ...
