About Common ragweed
Ambrosia artemisiifolia, commonly known as common ragweed, is an annual herbaceous plant belonging to the Asteraceae family. It is characterized by its deeply lobed, grayish-green leaves and small, greenish flowers clustered in terminal spikes. Although it is an invasive plant and a producer of allergenic pollen, its presence is more common in abandoned fields and roadsides than in ornamental gardens.
Native range
North America
Care tips
As Ambrosia artemisiifolia is considered an invasive weed and a significant source of allergenic pollen, its cultivation is not recommended. If it appears in your garden, it is best to eradicate it to prevent its spread and minimize allergy problems. It spreads easily by seeds, so manual removal before flowering is the most effective method.
