Notes: Called “Povertyweed” because it tolerates poor, salty soils, and known as “Deathweed” and “Devil’s Weed” because it an enthusiastic grower that crowds out other plants. The meaning or etymology of “Bozzle” is a mystery. Interestingly, each flower-head has separate male and female flowers inside it.
