Lassen Paintbrush

The Lassen Paintbrush (Castilleja lassenensis) is a captivating subalpine wildflower endemic to the volcanic slopes and high meadows of Northern California, particularly around its namesake, Lassen Volcanic National Park. As a member of the broomrape family, this perennial herb exhibits a fascinating hemiparasitic lifestyle, utilizing subterranean root connections called haustoria to siphon water and essential nutrients from neighboring grasses, lupines, and shrubs. Despite its parasitic habits, it is fully capable of photosynthesis, showcasing a brilliant balance of self-sufficiency and opportunistic adaptation. In late spring and summer, this species paints rugged volcanic landscapes with vibrant clusters of magenta and pink-purple, serving as an important nectar source for high-altitude pollinators.

Lebensraum: Found in rocky subalpine and alpine volcanic meadows, gravelly scree slopes, and open coniferous forest edges of the southern Cascade Range.
