Bogs, streams, and springs. Flowering Jun–Aug. 100– 1500m. Sisk. CA. Native.

Vollmer’s lily is quite variable, and phenotypic expression is highly dependent on environment and soils. Around the geographic edges of this range, identification becomes more difficult, and ssp. vollmeri intergrades with other subspecies of pardalinum along all its boundaries to produce morphologically jumbled intermediates. Even within the core range of the subspecies, plants in deep shade generally have scattered, wider leaves that much resemble ssp. pardalinum. Like most L. pardalinum, Vollmer’s lily is pollinated in Oregon by pale and western tiger swallowtails and also visited by rufous hummingbirds.

Wet meadows, lakeshores, streamsides in coniferous forests. Flowering Jun–Aug. 1200–1800m. Casc, ECas. CA. Native.

Subspecies shastense is in essence a smaller and less clonal version of ssp. pardalinum with smaller flowers, less exserted and spreading stamens, and brighter pollen. The very small plants from Lake of the Woods in Jackson County have been collected for decades. The northern limits of ssp. shastense are reached around Daley Creek in Jackson County and Lake of the Woods and Pelican Bay in Klamath County; some of these populations are variable and display the malformed flowers characteristic of Lilium pardalinum introgression zones. To the north, ssp. pardalinum eventually prevails around the town of Prospect and near Agency Lakes respectively, but in the intervening area, identification to subspecies may not be possible.
