Lilium occidentale Purdy is an endangered lily restricted to seeps and bogs of the coastal prairie, scrub, and coniferous forests of Del Norte and Humboldt counties in California and adjacent Oregon. It is pollinated by hummingbirds. Although threatened, it can be grown in cultivation. The first photo by Ron Moodycliffe at a residence in Oregon City, Oregon. The second and third by Ron Parsons were taken from a small population in Humboldt County, CA.
Lilium parryi S.Watson is commonly known as the Lemon Lily, is native to the foothills of the San Gabriel Mountains in southern California. In the wild, the plants grow in meadows and seasonal streams in montane coniferous forests of southern California. Photos 1-2 below, by Ron Parsons, are from a population in San Bernardino County, California, taken in late July, 2005. In cultivation, the bulbs should be kept moist throughout the year. This plant is a favorite of slugs and susceptible to Narcissus Bulb Fly. Photos 3-6 were taken by Nhu Nguyen. Photos 7,8 and 9 by Darm Crook, photos 10-11 of bulbs by Pontus Wallstén.
Lilium parvum Kellogg is found in various forms and colors in California's Sierra Nevada at elevations from 2500' to 9000'. Photos below were taken by John Longanecker.
Photos below were taken by Ron Parsons from plants growing at various localities in El Dorado County, CA.
Lilium parvum var. hallidayi is the name sometimes given to a pink form that is valued by gardeners but not recognized in current taxonomy; seedling photos 1-3 below were submitted by Darm Crook; they grow in his zone 1 gardens. Photo 4 of a bulb by Pontus Wallstén.
Lilium philadelphicum L. is found across the northern United States and into Canada, as far North as Ft. McMurray Alberta, from Maine to eastern British Columbia. It is also found in the Southern end of the Alaskan pan handle and on Vancouver Island BC. Canada. The western populations have leaves scattered along the stem, and are separated as var. andinum. The eastern populations (var. philadelphicum) have whorled leaves. The first photo from Rodger Whitlock is of a plant grown from seed received as Iris lacustris. It took a number of years from seed before it flowered so a proper identification could by made. The next four photos by Ron Parsons of plants in Manitoba, Canada.
Lilium philadelphicum var andinum Ker Gawl. Photos by Darm Crook showing some of the diverse colours and forms; it seems no two seedlings of this variety are ever alike. To survive and do well at Hay River NWT.Lilium philadelphicum var andinum needs an alkaline soil, right around a 7.5 pH, well drained, 50/50 high humus sand mix and full sun. Between L. philadelphicum and its variety andinum this lily probably has one of the largest natural geographic growing ranges of all the Lilium species excepting possibly L. martagon and its varieties. So it appears to thrive in nature but is a hard lily to grow in cultivation.
Lilium pitkinense Beane & Vollmer is considered by The Plant List and the Jepson Interchange to be a subspecies of Lilium pardalinum. See the Lilium pardalinum page.
Lilium rubescens S.Watson is a native, endemic species found in California. It is commonly known as the Redwood Lily. Photos 1 to 4 below are from populations in the wild, by Ron Parsons. Various localities in Mendocino, Humboldt, and Sonoma Counties, California. Photo 5 of a young bulb and photo 6 of a flowering size bulb by Pontus Wallstén.
Lilium superbum L. has a wide distribution in eastern North America. The first photo taken by Wayne Crist is of a plant, from a commercial source, that grows in the garden of Jim McKenney near Washington, D.C. This species still grows wild in this area, although it is as rarely seen in the wild as it is in local gardens. The plant shown was flowering for the first time: mature plants are among the most spectacular of lilies. The second photo by Ron Parsons shows plants in cultivation at the UC Botanical Garden. Photos three to five submitted by Darm Crook of a seedling that took 6 years to first flower in 2010. Photo 6 of a bulb by Pontus Wallstén.
Lilium washingtonianum Kellogg grows from central California to almost the border of Canada on steep forested slopes in the Sierra Nevada and Cascade ranges. Flowers are fragrant, trumpet-shaped, and open white, fading to pink or purple. Photo 1 was taken at Mount Hood by Ron Moodycliffe, photos 2-3 were taken by John Longanecker. Photos 4-5 were taken by Ron Parsons of plants in situ, El Dorado and Butte County, California. Photo 6 was taken by Nhu Nguyen of a form found in Tuolumne county, California.

Lilium wigginsii Beane & Vollmer is a synonym of Lilium pardalinum subsp. wigginsii (Beane & Vollmer) M.W.Skinner. See the Lilium pardalinum page.
