Here's only photo I can locate and much to distance!

Conifer50

That's the one I should've used instead of Bosnian Pine! I don't see it much around here, but it's a handsome pine. I'm not sure it would be worth planting here, as it would get lost among the abundance of native white pines.

How do we know this specimen is correctly identified?

Well, I don't, but Conifer50 likely does.

I think all of the "hardy ayacahuite's" probably have just enough Pinus strobus genes to handle the "cold" and retain the Mexican White Pine phenotypes!

Ron, it's definitely P. ayacahuite -- can't you see the distinctive cones near the top? (▰˘◡˘▰)

Conifer50, I assume that's Westtown right outside of Philadelphia?

Hi beng, it's only 20 miles west of Philly! I 've got several grafts with the scions being from Westtown clone. I'd like to compare Westtown "cones" with Masonic

Village cones located at Elizabethtown, PA.

Yes I wonder if pure Pinus ayacahuite is able to persist in PA.

best on well-drained moist loamy soils on relatively cool, moist sites, such as in riparian areas

Hardy to Zone 7

Pinus ayacahuite

The site mentioned above seems to say the Guatemalan stands are about as high in elevation or higher than the others populations, so again, really doubt it would be hardy in PA.

Hi Todd, if you obtained your "ayacahuite" seed from Sheffields they were supposedly harvested at about the 9000' on eastern slope of Volcan Tacana, Guatemala. I tried growing this "variety" when first offered and they were in 1 gal. pots and about 12" plants in ground. The first 15* F freeze resulted in 100% loss!

Both Pinus ayacahuite and Pinus veitchii seem to have a second flush and never harden off.....this could be resulting from late fertilization so I intend to eliminate that possibility! I'm going to try a "variety" from Hidalgo, MX this up coming spring.

I got my seeds from jl hudson. They were new to his catalog last year, I'd guess from 2016 or 2015. I asked about the provenance he was not more specific than guatemala. So I guess, using the conifers website above, somewhere between 2500 and 3000 meters of elevation. I'd like to get some seed for stylesi.

Our cold snap didn't bother my patula seedling, which is also in a plastic nursery can, or my pinus johannis which ive had fot many years and never protected. The maximartiezii seedlings I have come inside when it freezes. But i don't think they would have made it. I will eventually graft maximartiezii onto edulis then maybe I'll test their hardiness here

Also looking for p Nelsoni or culminicola if anyone sees seed available

Last year when I started these someone pointed out that guatemala also has pinus chiapensis. I have no reason to believe mine are not true to type yet but it may be worth mentioning that whoever collected them could have mistook one white pine for the other... chiapensis is truly tropical I think. But again I have no reason to think that happened.

I wouldn't leave anything like these out in unprotected pots during serious cold as potted plants are much more vulnerable.

I'm way behind here. Is it Pinus ayacahuite?

Patula is safe in the teens. I should have brought the ayacahuite seedlings in. It annoys the wife when I take all thus stuff inside. I need a greenhouse.

Has anyone here in the states tried pinus Montezumae? Supposedly it grows at altitudes up to 3200 meters (2 miles) in mexico. Those trees should be hardier than the stated 20F

Maakia I would guess no. A tree that size in PA would have to have seen low single digits right? Maybe less than 0?

The trunk does not look like P. Strobus. In any case, Embo was skeptical for good reason.

Todd, I think P nelsonii is available.

Where did you find it?

Nuevo Leon, MX

Well thats a good place to find them. I'd be happy to buy some off you. 7 toddcharlie at gmail is my Addy

whaas, the tree is prb'ly P. strobus x ayacahuite, given it has grown well in PA & weathered some very cold winters there (1994 & 1996 for ex).

Below is a P. strobus x wallichiana in west MD:
