blue on many plant.. is just a wax on the leaf surface... it can easily be washed off ..

the most common reason.. is overhead watering.. in the heat of summer ...

does the nursery water overhead???

it is genetic... it is not going to change due to plant CULTURE... as in more sun.. or more shade ...

Pinus koraiensis .. is sublime.. blue or not ... you should have at least one ... but it is a pine.. that has vast potential .... i hope you have room to site it properly .....

see link for conifer kingdom info and pic about such .... on another page they say:

Growth Rate: 6-9" ; HxW@10yrs: 8'x4'

which i read that it grows 6 to 9 inches per year.. for up to the next hundred years.... all size estimates are at 10 years.. double for 20 years ... triple... etc ...

I have one that's about 7 feet tall growing in afternoon shade and it is mostly green with only a tinge of blue. It was 4 feet tall when I bought it 4-5 years ago. I do like the somewhat compact narrow habit it has.

Pic from last year...

The trunk next to it is a now officially dead Pinus nigra and this is it's replacement.

All my Korean Pines have the same color as TJs, including Morris Blue.

My Pinus cembra seem to have a stronger blue tinge.

Either way a Korean Pine is a must for any landscape.

You want a Korean pine that's blue, 'Anna' is the one.

It's one of the prettiest species pines, as well. Not sure why they're not more popular. There's a big one in the tree collection at Hidden Lake Gardens that's gorgeous.

Dax, do you have Anna? Mine is green...although mine is from Girards who is well known for selling incorrect cultivars.

whaas, you may be happy to learn that Girards will be selling incorrect cultivars no more. Seems they have repurposed their business.

Thanks all. It will be replacing a orange bark Stewartia that did not make it through this past winter. I have never done mail order. But maybe I will give it a shot, or drive 3 hours to Broken Arrow in Connecticut. I am in New Jersey.

Try Burke Country Farms in Freehold NJ. They have 100s of different conifers there with a few hard to find varieties.

whaas, I've been to the ortet tree many times. It's blue, and I mean really blue. Never green at any time of the year.

Like so!

Coach, I did a search for Burke Country Farms in Freehold. Nothing came up. Do you have a phone # for them? thanks
