Araucaria araucana
Origin and Habitat
The Araucaria araucana, commonly known as the Monkey Puzzle Tree, is native to the temperate rainforests of Chile and Argentina, particularly in the Andes mountains. It thrives in volcanic soils and cooler climates, often growing at high elevations with significant rainfall. This tree is considered a living fossil, with its lineage dating back to prehistoric times. It is protected in its native habitat and is considered endangered due to deforestation and land conversion.
Description
Araucaria araucana is a striking evergreen conifer with a distinctive pyramidal shape, capable of reaching heights of 120 feet in the wild, though it typically grows to around 36–72 inches in cultivation. Its dark green, sharply pointed leaves are arranged spirally around thick, sturdy branches, creating a dramatic architectural look. While it rarely flowers in cultivation, mature female trees produce large, rounded cones with edible seeds, whereas male trees develop narrow, cylindrical pollen cones.
Cultivation
Zone: Hardy in USDA Zones 7–10
Temperature: Tolerates -20°C to 30°C
Growth Rate: Slow to moderate
Soil: Prefers well-draining soil amended with pumice for aeration and drainage
Watering: Keep soil consistently moist but not soggy; reduce watering in winter
Fertilizing: Feed with a balanced liquid fertilizer every 2–3 weeks during the growing season
Light: Thrives in full sun to partial shade
Pests and Diseases: Generally pest-resistant; occasionally affected by root rot if overwatered
Propagation
Propagation is best achieved through seeds, which should be sown fresh. Germination may take several weeks and requires moist, warm conditions. Cuttings are possible but have a low success rate and are not commonly used.
