The true full name is
Pinus parviflora 'Azuma', in the past 'Azuma-goyo'.

The "Pent" part is a shortening for Pinus parviflora var. pentaphylla, which was a natural variety but is now not distinguished from the species...

Thanks - do you grow it or have pics?

Not much info online. Looking for an idea on habit/size after 10 years or so. Fairly irregular in shape right now.

I don't understand the significance of "pentaphylla" which means five-needles when the species parviflora already has five needles..

Anybody want to explain that one?

Here you can see a few pics...

They may be the same plant in Europe, but they are not here. Pentaphylla Azuma grows at a much faster rate than I had anticipated and is more upright. The ACS database confuses the form. Azuma-Goyo is a tight, more horizontal and very blue form.

size estimates are at 10 years.. divide by 10 for annual growth rate ... or do what i did at the link ... second link suggests 6 inches per year on becoming established.. and that sounds about right on parv's across the board.. but reduced for variegation ...

you may 'see' that.. if you look closely at your plant.. from prior years growth.. though being potted and all.. maybe not ...

generally speaking ... most parv's are not xmas tree shaped.. they kinda do their own thing.. unless guided by you ...

i would refer you to the intro to conifers at the ACSoc but i am only allowed one link ... for a discussion of annual growth rates ...

i would also link you to a planting guide.. do you need that..

what is your native soil ... clay means things ...

a pic might help ID the thing.. never really know if tags are correct ... but the peeps here have keen eyes ... especially the joy-ful one ... as to cultivars ...

and finally.. bargain means its been sitting around all year.. do you know about root surgery.. and all that????

Thanks for the info guys.

Baxz5oh - that's what I was thinking...while young, the habit of this thing is shrubby/horizontal. Reminds me of pinus pumila.

Ken - came from Hopper Bros in Oregon, good nursery. My native soil is a nice sandy loam - we are the "fruit bowl of the nation". W/ help from irrigation of course.
