A Sourgrass weed grows through a crack in the cement along Pico Blvd. on Wednesday, February 27, 2008. These weeds have a pleasant lemony taste and are sometime used to season salads, and in herbal remedies. Pulling the weed up does not kill it. It is the bulbrils in the ground which send out rhizomes and readily resprout. This plant is highly invasive and should never be planted near any rural or pastoral area.
