wavy-leafed soap plant
Chlorogalum pomeridianumAlso known as California Soaproot, Amole, Soap Plant
Wavy-leafed soap plants are distinctive California perennials easily recognized by their ground-hugging rosette of long, crinkled leaves with highly undulated margins. During the heat of summer, they send up tall, branching stalks that produce delicate, star-shaped white flowers opening only in the late afternoon to attract nocturnal pollinators like bumblebees and moths. The underground bulb is wrapped in a thick, coarse coat of brown fibers, historically utilized by Indigenous peoples to make versatile brushes and a rich, lathering soap.
