Discover the majestic Juglans regia, commonly known as English or Persian Walnut, a broadleaf deciduous tree celebrated for its delectable nuts and ornate presence. Reaching heights of 40 to 60 feet with an equally expansive spread, this species boasts a rounded crown that embellishes landscapes. Its gray bark evolves to reveal striking ridges as it matures, while the pinnately compound leaves, featuring a citrus fragrance when crushed, add a sensory delight to your garden.
Originating from Europe and Central Asia, J. regia thrives in rich, well-drained soils under full sun. This regal tree, valued for its fine-grained wood, plays a significant commercial role in California, producing 99% of the U.S. walnut supply. Blooming with yellow-green flowers from May to June, English Walnut produces thin-shelled, wrinkled nuts encased in green husks, ripening by fall.
Species of choice for larger landscapes, Juglans regia is not only a source of sweet, edible nuts but also a beacon of biodiversity, serving as a host to the Hickory horned devil moth larvae. While it is intolerant to shade, hot humid climates, and difficult to transplant due to its deep taproot, its illustrious appearance and utility earn it a royal place among ornamental trees.
