Lilium humboldtii is a type of lily native to California. It is also known as Humboldt's lily, and was named after Alexander von Humboldt, a naturalist and explorer who first described the lily to western botanists. It occurs in South High Cascade Range, High Sierra Nevada, south Outer South Coast Ranges, and Southwestern California.
It is less than 3 m tall. The flower is maroon-spotted, golden-orange with dark red splotches, with orange to brown stamens. The flowers are on stout stems, which are sometimes brown-purple. The population is declining. It is summer-deciduous, dying back after flowering in mid- to late summer.
