Ambrosia, also known as ragweed, is actually more common in North America. But here in Germany, there are also some Ambrosia species that spread invasively in home gardens.
The plant is currently found in the south of Germany, although populations have also been reported further north, such as in the Berlin area. It is so dangerous for Europeans because, according to the Bavarian State Institute for Viticulture and Horticulture, the pollen allergen is much stronger than that of European plants. Allergy sufferers have a much stronger reaction than to the plants they are used to. Skin contact with the plants can also cause irritation, red spots, or even inflamed eczema, which must be treated with cortisone ointments. This is how you can identify and eliminate the dangerous weed from North America and other plants that look similar to ragweed in German gardens.
