Plant
Walnut
Juglans regia
Also known as: Juglans regia, Persian walnut, English walnut
A deciduous tree in the walnut family (Juglandaceae), native to the mountains of Central Asia (modern Iran, Afghanistan, Tajikistan) — domesticated and spread along the Silk Road. The black walnut (*Juglans nigra*) is the North American relative, distinct in flavor and ecology. The walnut tree is allelopathic — its roots and leaves produce juglone, a compound that suppresses growth of many nearby plants. The nut is the principal commercial product; the wood is one of the most prized hardwoods for fine furniture.
Scientific
Juglans regia is the common cultivated walnut globally — the “Persian” or “English” walnut. Juglans nigra ([[black-walnut|black walnut]]) is the North American native species, with darker, stronger-flavored nuts and the most prized walnut timber.
The species is allelopathic — Juglans root and leaf chemistry produces juglone, which inhibits the growth of many nearby plants (tomatoes, blueberries, and several other common garden species are notably susceptible). This is part of why walnut groves tend toward monoculture in their understory.
Cultural
Central Asian / Persian origin; the species spread west along the Silk Road into the Mediterranean (Greek and Roman cuisines knew the walnut) and east into China. Walnuts appear in Persian poetry, Mediterranean cookery, and (later) European holiday baking traditions.
Global production
Top producers: China, USA ([[berkeley|California]]), Iran, Turkey, Mexico.
