Ragweed is a weed that can be found from May to October. It starts to flower in mid-July, releasing fine dust-like pollen into the air. This dust causes allergic reactions in sensitive individuals.

Ragweed pollen is the main cause of the seasonal rhinitis that affects one out of every seven Quebecers.
