About Turpentine Weed (Trichostema laxum) 0 Nurseries Carry This Plant Trichostema laxum is a species of flowering plant in the mint family, known by the common name turpentine weed from the foliage's scent. The annual plant is native to northern California and Oregon, at elevations below 1,700 metres (5,600 ft). It is found primarily in the Inner Northern California Coast Ranges, including the subranges of the Klamath Mountains and the Mayacamas Mountains.
