Pinus montezumae aka Montezuma Pine

Pinus montezumae, or Montezuma pine, belongs to the pine family, Pinaceae. This evergreen tree comes from Mexico and Guatemala. It grows in mountain forests, often with oaks. It has a long life and one straight trunk. Young trees have a cone-shaped crown. With age, the crown rounds out and lower branches spread. Growth is moderate. The species remains widespread despite large-scale timber harvests. Its reported conservation status is Least Concern.

Allow space for a tree around 70–100 feet [21–30.5 metres] tall. Its spread can reach 40 feet [12.2 metres]. Broader accounts give heights up to 131 feet [40 metres]. Mature bark has deep cracks. Blue-green needles form dense clusters at the branch tips. Most bundles, called fascicles, hold five needles. Each needle can reach 0.6–1 foot [0.18–0.30 metres] long. The needles may point out or hang down. Their length and clustered growth give the branches a full look.

This conifer makes cones rather than flowers. Wind carries its pollen, and the tree is not self-fertile. Its light brown cones have stalks and take two years to develop. Their shape ranges from egg-like to cylindrical. Cones measure about 0.2–0.7 feet [0.05–0.20 metres] long. Each cone scale bears a small spine. The dark brown seeds are small. The available account does not establish their value as food. It does report a vanillin flavouring derived from pulpwood resin by-products.

Grow Montezuma pine in full sun, not shade. Moist loam with good drainage suits it well. It also accepts sandy loam and clay loam. Avoid ground where water sits around the roots. Garden watering needs are moderate, though established trees can withstand drought. Missouri Botanical Garden lists USDA zones 9–11 for winter hardiness. This large tree needs a large site. Its evergreen crown adds interest through winter. The same source lists low upkeep and resistance to deer. It reports no serious insect or disease problems.

The tree supplies timber from both wild stands and plantations. People also use it in local traditional medicine. Its needles can yield tan or green dye. Seed offers a means of propagation. Fresh seed is best sown in separate pots when ripe. Stored seed may sprout better after six weeks of cold treatment. Plant young trees in their final sites while small. Their sparse roots make early planting important.
