Trichostema lanatum, the woolly bluecurls,[1] is a small evergreen shrub or sub-shrub native to arid coastal chaparral regions of California and the northern parts of Baja California.

Trichostema lanatum is many-branched and grows to 1.5 m (5 ft) tall, with narrow, pointed green leaves. The smooth-petaled blue flowers are borne in dense clusters, with the stem and calyces covered in woolly hairs of blue, pink, or white. Flowers are present from March to June.[2]

Spanish explorers in California called the plant romero, the Spanish term for rosemary, and that common name is still sometimes used.[3]


Trichostema lanatum is cultivated as an ornamental plant, and several cultivars have been developed.[3] It attracts hummingbirds and bumblebees.[4]

It is aromatic and glandular. Native Americans used it for a variety of medicinal and other purposes.[5]

It makes a flavorful tea.[3]
