Varieties

;Recognized cultivars
*''Lilium maculatum'' var. ''bukosanense'' (Honda) H.Hara
*''Lilium maculatum'' var. ''maculatum''

The variety ''bukosanense'' (Japanese: ) was originally discovered on Mount Bukō in Saitama Prefecture near Tokyo, with scattered populations later found in Ibaraki Prefecture. The variety is unusual, as it is a "hanging" or "weeping" type with a pendulous stem, but is listed as critically endangered by Saitama's Red Data Book. The mountain has been heavily quarried for limestone by the cement industry, which now collaborates in the plant's conservation efforts in captivity; foraging by wildlife such as the Japanese macaque is also thought to jeopardizes its survival.

Japanese literature c. 1900 writes of several yellow varieties grown which had no spots, but a warning was written against their export, while only spotted or lightly spotted varieties of these yellow lilies were being shipped to the West. Years later, the spotless yellow lilies were still considered few and elusive.
