Lilium maritimum

Lilium maritimum is a species of lily known by the common name coast lily. It is endemic to California, where it is known only from the coastline north of San Francisco.[1] It formerly occurred south of San Francisco; these occurrences have all been extirpated. The species is now restricted to the North Coast from Marin County to Del Norte County, and is most common in Mendocino County.[2] It grows in the California coastal prairie habitat, coniferous forests, and bogs amongst Drosera species.[3]


Lilium maritimum is a perennial herb usually exceeding a meter in height and known to exceed two meters at times. Specimens from coastal bluffs and similar harsh habitats are much smaller. The plant grows from a scaly, elongated bulb several centimeters long. The oval leaves are mostly basal, with some located in several whorls about the stem. They may reach 18 centimeters long.[3]

The inflorescence bears up to 13 large, nodding flowers. The flower is bell-shaped with 6 tepals with tips recurved or curled tightly back. The tepals are up to 5 centimeters long and red to orange, usually with spots. There are 6 stamens with large red anthers sometimes over a centimeter long, and a pistil which may be over 3 centimeters in length.[3]


Lilium maritimum flowers are pollinated by Allen's and Anna's hummingbirds when first open, and later by bumblebees (Bombus spp.).[3]
