Rattan's leptosiphon is a California native annual found in northern coastal ranges in dry openings within conifer forest at elevations of 1,700 to 2,000 meters. Flowering from May to July, this delicate plant produces white flowers with distinctive maroon tubes and yellow throats, each bloom emerging singly on thread-like stems. Growing 5 to 20 centimeters tall with thin, generally hairy stems, it forms a delicate and intricate appearance in forest clearings. Its leaves have fine linear lobes 2 to 5 millimeters long, contributing to the plant's slender, understated structure. The flower's unique maroon tube with a yellow throat and white lobes creates an intriguing color contrast characteristic of this subtle woodland species.
