You might hear American pokeweed referred to by a variety of names, including phytolacca Americana, poke sallet, and dragon berries. It’s a significant allergen that affects hayfever sufferers. Giant ragweed produces a large amount of fine pollen that’s spread easily by the wind. Seed dispersal occurs through spiky burs that people, animals, and water, carry to new locations. The upper stems end in a spike of small yellowish-green flowers arranged in drooping clusters around the spike. And the large leaves have 3-5 lobes and grow up to 12 inches across. The thick green stem has a coating of fine white hairs. This is a tall plant that grows between 3-12’ tall with occasional branching. And it’s destructive to other plants in the areas it invades as it outcompetes them for sunlight and puts them in the shade.
It’s widely considered to be a noxious weed.
You can also come across it in Europe and Asia where it’s an introduced species. This annual weed is a North American native that’s found in many parts of the US, Canada, and Northern Mexico. How Do You Get Rid Of Tall Weeds With Thick Stalks? Giant Ragweed
