This perennial forb, found in almost all areas of Texas, is probably the most famous allergy plant. Pollen of Western ragweed is very light and easily air borne which makes it a real challenge for those with allergy issues. However, instead of relying on pollinators like bees for pollination, Western ragweed relies on the wind to carry its pollen from plant to plant.
Western ragweed reproduces both from seed and from new plants that develop from lateral roots that run two to four inches below the ground surface. Mature plants can grow from one to two feet tall. To read more pick up THE April 2016 issue of NTFR.
