Montezuma pine (Pinus montezumae) is native to Mexico and Central America and grows in the mountain ranges. This tree is known as ocote by the locals of Mexico. This tree has been planted successfully at mid altitudes in South Africa and Queensland, Australia, and at high altitudes in Kenya, Malawi, Botswana, Zimbabwe, and Bolivia. Trees planted in New Zealand and New South Wales, Australia have done well at sea level. The Montezuma pine grows at 6,562-10,500 feet above sea level where...
Macedonian Pine (Pinus peuce) is native to Macedonia, Bulgaria, Albania, Montenegro, Kosovo, southwest Serbia, as well as the extreme north of Greece. This pine has been neutralized and grows in Eastern Finland. This pine grows best at altitudes between 3,281feet and 7,218 feet with a few growing as low as 1,969 feet and as high as 7,546 feet. This pine tolerates shade as well as extreme cold, and grows in rocky soils that are acidic and poor in nutrients. This tree grows to heights...
Limber Pine (Pinus flexilis) grows in the sub-alpine mountainous regions of the Western United States, Mexico, and Canada, with a small cropping found in the Black Hills in South Dakota. One of the oldest trees to be documented is found in Eagle Cap Wilderness in Oregon and is reported to be 2000 years old. This pine is also known as the Southwestern White Pine and Rocky Mountain White Pine. The Limber pine is drought tolerant and grows at high elevations (5000-12,000 feet) marking the...
