About
Chlorogalum pomeridianum, the wavy-leafed soap plant, California soaproot, or Amole, is the most common and most widely distributed of the soap plants, soaproots or amoles, which make up the genus Chlorogalum of flowering plants. It is occasionally known as the "wild potato", but given the plant's lack of either resemblance or relationship to the potato, this name is not recommended.
It is found in most of California from the coasts to the western foothills of the Sierra Nevada, and in the Klamath Mountains in southwestern Oregon, but not in either state's desert regions. Wavy-leafed soap plant grows on rock bluffs, grasslands, chaparral, and in open woodlands.
Uses
The fibers surrounding the bulb were widely used, bound together, to make small brushes. Extracts of the bulbs could also be used as a sealant or glue.
