Vinegar Weed

 Trichostema lanceolatum (camphor weed) at Lake Santa Margarita

Vinegar weed is a very interesting plant. It has small elongated leaves and relatively big flowers with long parts sticking out. It was obviously a plant of the mint family. I was lucky to identify it very soon after I took a picture: the plant in question is called Trichostema lanceolatum, part of the Mint family (Lamiaceae). Like other mints it has square stem. The common name is not quite right. The plant indeed has a very strong smell, it feels juicy to the touch but I would not describe it exactly like vinegar smell. The smell is quite pleasant though pungent. That pungent smell is referred to in common names like turpentine weed and camphor weed. Camphor smell would probably be the closest description. As far as I know it is not edible.

Trichostema lanceolatum grows in dry hard soil in hot climate

The plant is striving in hot climate in dry soil though so far I have only seen it in one place: Lake Santa Margarita where the photographs have been taken. I read that the smell is produced by volatile oils and these oils also help to keep other plants away.

Notice the similarity to another plant called wooly blue curls. The Latin name for that one is Trichostema lanatum. Notice the same genus, Trichostema.The latter plant is extremely rare.
