Today's featured Weekly Weeder plant is common ragweed, Ambrosia artemisiifolia.
Common ragweed is also known as ragweed, hayfever weed, bitterweed, bloodweed, crownweed, mayweed and bane of allergy sufferers everywhere. Some other common ragweed species include bur ragweed, giant ragweed and western ragweed. Western ragweed is a perennial.
The seeds of this amazing plant can lie dormant in the soil for 40 years, waiting to be unearthed to spread truckloads of tiny pollen grains EVERYWHERE. Plus – bonus – changing weather patterns have extended the ragweed season through much of the United States. (BTW, just for the record, the climate has been changing as long as the planet's been around. The weather has raised and toppled empires – but that's another post.)
