White pine needles turning blue??

Posted by catherinet z5 (My Page) on

I bought 3 of these white pine trees (about 2-3' tall, 3-4 years old) a couple weeks ago. We haven't been able to plant them yet. They are in something like 3-4 gallon pots.
They've been getting some sun and shade and I haven't watered them recently, because we've gotten alot of rain.
The other day I noticed one of them has needles that are getting light blue in color. Now all 3 of them are getting this color. The branches aren't drooping.
What might this mean? If there's something wrong with them, I'll take them back and not waste my time planting them. Hopefully you can see the picture well enough.
Thanks.

Normal, happy white pine. The blue color comes from wax on the needles' surfaces. Some seedlings have more than others. Most people find them to be more attractive than the yellowish-green ones.

Cool! I was so afraid it meant something bad!
That's great news. Thanks!

Is the one at the pic a "normal" seedling of Pinus strobus or is it a grafted cultivar?
What name was mentioned on the tag?

Could it be Strobiformis rather than Strobus?

I checked the label today and it said Strobus. Eastern White Pine. What happens if it is the Strobiformis? I've planted alot of small pines and I've never seen them this blue.

There is no reason to believe it is strobiformis. White pines with silvery needles occur all the time.

The reason for the colour change just now, is the new needle fascicles opening. When they first emerge, the 5 needles in each fascicle are tight together, only showing their green outer faces. Then when they're nearing full length, they start to spread apart, showing their blue-white inner faces as well.

Thanks everyone.
One thing that concerned me was that new needles pulled out very easily. I went out to the field where I had planted other younger white pines 1-2 years ago, and to my surprise, all their new needles pulled out very easily.......as did the new growth on the much older pines! So I guess I won't use that as a sign that a tree isn't doing well!
