Chlorogalum parviflorum is a monocot, native to coastal southern California and Baja California, where it is a member of the coastal sage scrub flora.
It is a perennial wildflower, growing from a dark-coated bulb several centimeters wide. The basal leaves have wavy edges.
The inflorescence may reach 90 centimetres (35 in) tall, and is made up of many dark-veined white or pinkish flowers. Each flower has six tepals just under a centimeter long which are spread open for only one day. The six stamens are tipped with yellow anthers.
The fruit is a capsule a few millimeters long.
