Monardella undulata grows as a small shrub up to 2.5 m (8 ft) across.

Its branched stems are 10–100 cm (4 in – 3 ft 3 in) long, and vary from sparsely hairy to being covered with dense, matted, woolly hairs giving a white appearance (tomentose).

The flowers are strongly scented, arranged in terminal spikes, 10–30 mm (0.4–1.2 in) wide, and vary from straw-colored through lavender to rose-purple.

[1] Subspecies include: It is endemic to the coast of California from Sonoma to Santa Barbara Counties, where it is known from several coastal habitat types, including dunes, coastal sage scrub, chaparral, and forest.

This species is an important food plant for the endangered Myrtle's silverspot butterfly (Speyeria zerene myrtleae), which eats its nectar.
