Juglans regia Description

Juglans regia, common or English walnut, is a large deciduous tree with a broad spreading crown and aromatic pinnate leaves. Inconspicuous spring flowers develop into rounded green husks containing the familiar edible walnuts, usually ripening in autumn. Mature trees can exceed 12 metres high and spread more than 8 metres, so allow generous space away from buildings and small borders. Grow in full sun in deep, fertile soil that remains moist but drains freely. A warm position helps nut development, and young spring growth can be damaged by late frost. Seed-grown trees may take many years to crop and can vary in productivity. Pruning should be kept to a minimum, as large cuts may bleed heavily and mature walnuts develop their best shape naturally.
