Burbank™ Royal Black Walnut Tree

Burbank™ Royal Black Walnut carries one of the most celebrated names in American plant breeding — developed by Luther Burbank (1849–1926), who spent over 50 years creating plant varieties that transformed American agriculture and horticulture. This black walnut delivers large nuts with distinctive light, cream-colored kernels — milder in appearance and notably attractive compared to the darker kernels of most black walnut varieties — from a fast, vigorous tree that’s cold-hardy to -10°F and grows into one of the most impressive landscape trees available. At 60–80 feet tall, the mature tree produces furniture-quality hardwood alongside its annual October nut harvest. Grafted, self-pollinating.

Important: As with all black walnuts (Juglans nigra), Burbank™ Royal produces juglone — a natural compound that can inhibit the growth of certain nearby plants. Plant away from fruit trees, tomatoes, and other juglone-sensitive plants, and allow adequate space for the mature canopy.

Light Cream-Colored Kernels — A Distinctive Black Walnut

Most black walnut kernels are dark — the characteristic amber-to-brown color that comes with the variety’s bold, assertive flavor. Burbank™ Royal’s large kernels are notably lighter, with a cream-colored appearance that makes them visually distinctive and appealing in baked goods, confections, and presentations where the kernel’s appearance matters alongside the flavor. The same rich, bold, deeply flavored black walnut character — in a more striking package.

A Legacy of Exceptional Varieties

Luther Burbank was one of the most prolific and celebrated plant breeders in American history — responsible for over 800 plant varieties including the Shasta Daisy, the Russet Burbank potato, plums, peaches, and numerous other varieties still in cultivation today. Burbank™ Royal Black Walnut carries that extraordinary pedigree, developed by a breeder whose entire career was dedicated to finding and sharing the finest plants available.

Fast-Growing, Cold-Hardy, Furniture-Quality Wood

The combination of fast, vigorous growth and cold hardiness to -10°F makes Burbank™ Royal one of the more accessible large black walnuts for northern home orchardists. The mature 60–80 foot tree produces some of the finest hardwood in North America — dense, beautifully grained, and prized for furniture, cabinetry, and gunstocks — making it a genuine multi-generational investment in both nut production and timber value.
