Pinus Strobiformis - SW White Pine

I had a few in Arkansas, in the ground, not in pots. Looks like you should treat them pretty much like a Japanese White Pine, quick draining soil, protect from intense heat. In the "decandling" in black pines, can break long candles / buds to control growth (remember it is the stimulated shorter regrowth that is kjey).

Mexican white pine, Chihuahuan white pine, southwestern white pine; pine, pine, pine, pine

Taxonomic notes

Syn: Pinus ayacahuite Ehrenberg var. brachyptera G.R. Shaw; P. ayacahuite var. reflex (Engelmann) Voss; P. ayacahuite var. strobiformis (Engelmann) Lemmon (Kral 1993). See below.

This is a typical white pine in section Strobus, subsection strobi. This species is closely related to Pinus flexilis, with which it forms the hybrid Pinus flexilis var. (Farjon and Styles 1997).

In 2008, Michael Frankis described a new species, Pinus stylesii Frankis ex Businský, from Cerro Potosí and neighboring mountain ranges, chiefly in Nuevo León, Mexico. I believe that this taxon is derived from the hybridization of P. strobiformis and P. flexilis, and has reduced it to synonymy with Pinus flexilis var. reflex, although in actuality it probably lies somewhere between typical P. flexilis var. reflexa and typical P. strobiformis. The full story is given on the P. flexilis page.
Description

US: Arizona, New Mexico, Texas; Mexico: Coahuila, Nuevo León, Sonora, Chihuahua, Sinaloa, Durango; at 1900-3000 m. Habitat dry rocky slopes in high mountains, or a minor component in mixed conifer forests. In the United States such habitat occurs on isolated desert mountain ranges, and in Mexico it is widespread in both the Sierra Madre Occidental and Oriental. Within habitat, it mostly grows on moist, cool sites with associates such as P. hartwegii, and P. culminicola (Little 1980, Perry 1991, Kral 1993). See also Thompson et al. (1999).

In the United States: diameter 150 cm, height 34 m, crown spread 19 m, located in Lincoln National Forest, NM (American Forests 1996). Oldest

Tree VPK02 collected in the San Mateo Mountains of New Mexico by Henri Grissino-Mayer, J. Speer, and K. Morino had a crossdated age of 599 years (RMTRR 2006).
Dendrochronology
Ethnobotany

The seeds were eaten by natives of the southwest US (Little 1980). It is locally (in Mexico) used for cabinetry, doors and window frames (Perry 1991). Observations

In the United States, it can be found near the summits of the Chiricahua Mountains and probably in other high ranges of southern Arizona. In Mexico, Perry (1991) recommends the following locations:

As far as I'm concerned, there is no shortage of restaurants in the area. No guides or fancy vehicles needed for these sites!
Remarks

White pine blister rust. (Cronartium ribicola), an introduced fungal disease, attacks this and other white pines (Little 1980).

This species is the primary hosts for the dwarf mistletoe Arceuthobium blumeri, which extends from southern Arizona south through Durango and east to Cerro Potosí in Nuevo León (Hawksworth and Wiens 1996).
