Allergy Facts

Giant ragweed requires rich, moist soils for growth and is rarely found in areas where low rainfall is common. Unfortunately, arid regions support different species of ragweed, such as Ambrosia dumosa (bursage), which makes dry regions just as miserable for allergy sufferers as wetter climatic zones.
