The Walnut and Butternut belong to this genus, both being noble park trees forming massive straight trunks and wide-spreading branches, while their handsome, pinnate, glossy leaves add much to their attractive appearance. There are several species including Juglans regia (the English Walnut), Juglans cinerea (Butternut), Juglans nigra (the Eastern Black Walnut), Juglans Californica and the Japanese species, Juglans Sieboldiana. All form grand park trees requiring considerable space for their proper growth and development as well as deep well-drained soil and sheltered situations.

Propagate by seeds planted, in Winter or early Spring, one inch deep in nursery rows. Transplant the seedlings to their permanent quarters when they are not more than two years old.
