Vinegar weed

Family: Lamiaceae · Type: annual · Native

Vinegar weed is a California native annual found in the California Floristic Province in dry, open, generally disturbed habitats at elevations below 2,200 meters. Flowering from June to November, this plant produces flowers with a distinctive curved corolla tube that sharply recurves near the throat, creating an unusual floral structure. Growing with slender stems up to one meter tall, covered in short appressed or long soft-spreading hairs, some of which are glandular. Its leaves are lanceolate to narrowly ovate, 2 to 7 centimeters long, with prominent lateral veins near the base and a length more than three times its width. The plant's stamens extend 13 to 20 millimeters beyond the flower, adding to its distinctive appearance.
