Kellogg’s lily occurs from Humboldt County, California, north to just over the Oregon border. Like Lilium bolanderi and L. pardalinum subspp. vollmeri and wigginsii, it is endemic to the Klamath Mountains.

Occasionally plants occur with one or more whorls coalesced into tufts with as many as 40 leaves. Plants in open chaparral are usually of small stature with compact inflorescences and the ascending leaves are undulate on the margins. Plants of forest gaps are larger, with open inflorescences and flat, horizontal leaves.

Lilium kelloggii is pollinated by pale swallowtail butterflies (Papilio eurymedon Lucas, family Papilionidae) and western tiger swallowtails (P. rutulus Lucas).
