Weed started to be visible 4 weeks ago. It has grown to 12-18 inches in diameter. Only one single root and it is straight down deep. It is choking out a customers buffalo grass. He showed me huge areas that it was last year and buffalo grass did not recover. It has small purple-grayish flowers on the tip of stems. It grows out, not up. It looks just like dried rosemarry leaves used in cooking, just slightly smaller. No aroma to speak of.
