Golden bowl mariposa

Family: Liliaceae · Type: perennial · Native

Golden bowl mariposa is a California native perennial found in the southern Transverse Ranges and Peninsular Ranges on dry, often granitic slopes in chaparral and yellow-pine forest at elevations of 600 to 2,500 meters. Flowering from May to July, this plant produces distinctive yellow flowers 30 to 50 millimeters long with dark red-blotched sepals, featuring delicate yellow hairs near the flower's nectary. Growing with straight, generally stout stems 30 to 60 centimeters tall, it emerges from a bulb with minimal bulblet production. Its leaves are primarily basal, 10 to 20 centimeters long and glaucous, with 2 to 4 cauline leaves that are 5 to 15 centimeters long and inrolled. The fruit develops as an erect, narrowly lanceolate capsule 5 to 8 centimeters long with distinct angular edges.
