Juglans pyriformis is a large semideciduous tree from wet tropical forests of Mexico and Central America, typically found on river banks up to about 1400 m. It is a forest timber tree rather than a garden or houseplant, so care is mainly about its tropical climate and room to grow.

About

Juglans pyriformis is a semideciduous tree species in the Juglandaceae family. It can be found in Costa Rica, Guatemala, El Salvador, Honduras, Mexico, and Nicaragua. It can grow up to 40 m in height and 1.5 m in diameter. The long branches bear twigs tipped with 40–50 cm long, glabrous, pinately compound leaves, darker on the top than on the bottom. The base of the trunk sometimes has buttresses.

Where it grows

Juglans pyriformis grows in wet and very wet tropical forests, most frequently on river banks, observed from 0–1400 m above sea level. Reports that it also grows in the mountainous regions of Argentina may result from confusion with the cedro negro (Spanish for "Black Cedar" due to its close appearance to West Indian cedar) or nogal (Spanish for "walnut") (J. neotropica).
