The Wavy-Leafed Soap Plant

Chlorogalum pomeridianum, the Wavy-leafed Soap Plant or California soaproot, 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 found in most of California, apart from the Sierra Nevada and the deserts, and also in south-western Oregon. 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. Wavy-leafed Soap Plant grows on rock bluffs, grasslands, chaparral, and in open woodlands.

Like all the Soap Plants, the Wavy-leafed Soap Plant is a perennial that grows from a bulb, which is brown, between 7 and 15 cm in diameter, slightly elongated, and covered in thick, coarse fibers. The leaves grow from the base of the plant, and can be from 20 to 70 cm long and 6 to 25 mm wide. As the plant's name indicates, their edges are generally wavy, though this is not always particularly noticeable. The flowers are borne on a long stem, normally longer than the leaves, and are from 15 to 30mm long. The six petals (actually only three of them are petals in the technical sense; the other three are sepals) are up to 35mm long and curving. They are typically white but have a noticeable mid-vein which can be purple or green in color. The six stamens are large and noticeable, and yellow or orange. The flowers are bisexual (include both female and male parts). They open only in the late afternoon or evening, remaining open during the night but closing by the morning. Pollination is by evening- or night-flying insects.
