Juglans neotropica
Also called Ecuador Walnut, Columbian Walnut, Ecuadorean Walnut
Juglans neotropica is a large, slow-growing forest tree from the Andes, reaching up to 40 m, grown mainly for timber and its walnuts rather than as a garden plant. It needs cool, humid, mountain conditions with fertile, loose soil and steady moisture.
Juglans neotropica is a species of flowering plant in the Juglandaceae family. It is a tree native Colombia, Ecuador, Peru, and northern and northwestern Venezuela. It is threatened by habitat loss. Common names include Colombian walnut, Ecuadorian walnut, Andean walnut, nogal, cedro negro, cedro nogal, and nogal Bogotano.
It is a slow-growing tree attaining heights of up to 40 meters (130 ft), with grooved, red-brown bark and an oval-shaped canopy. The compound leaves, typical to all members of Juglans, are about 40 cm (16 in) long, grouped at the ends of the branches, and have a serrated border.
The species prefers loose-textured, fertile soils, and seems to thrive in somewhat muddy conditions. Neutral to slightly acidic soils are ideal; the tree will not tolerate calcaerous soils nor very acidic conditions. Andean Walnuts are found between 1,600 and 2,500 meters (5,200 and 8,200 ft) of elevation, in biomes where the average temperature is between 16 and 22 °C (61 and 72 °F), and annual precipitation of between 1 and 3 meters (39 and 118 in) that is distributed evenly throughout the year. The species does particularly well when planted near running water. It is found naturally in a wide variety of Pre-Montane and Montane forests, and most abundantly in cloud forests.
