Trillium albidum (Giant white wakerobin) is a native California herb in the Melanthiaceae family, recognized by white petals, spreading orientation, and sweet fragrance.

Giant white wakerobin is a California native perennial found in northwestern California, Cascade Range, northern Sierra Nevada, and San Francisco Bay Area in redwood and mixed-evergreen forests, coastal scrub, and chaparral at elevations below 2,000 meters. Flowering from February to June, this plant produces white to pale pink flowers with occasionally purple bases, 4 to 8 centimeters long, with an attractive sweet rose-like or spicy fragrance. Growing 20 to 60 centimeters tall with green stems, it features distinctive large leaves that are sessile, rounded to obtuse at the tip, and often subtly spotted in brown or green. Its broad leaves measure 7 to 20 centimeters long and 12 to 15 centimeters wide, creating a dramatic appearance in forest understories. The fruit is pulpy and juicy, ranging in color from green to purplish green.
