Ambrosia (hay fever plant)
Ambrosia is a plant that does not originally occur in the Netherlands. In recent years, the plant seems to be spreading rapidly in the Netherlands, probably due to climate change. Its spread in the Netherlands is worrying because ambrosia pollen is the main cause of hay fever worldwide.
The plant spreads rapidly via birds, which is why it is often found in people's gardens. Because the plant flowers at the end of the hay fever season, people often suffer from hay fever for two months longer. That is why we want to prevent the plant from establishing itself on a large scale in our country.
