Dittrichia are flowering plants with small, yellow, daisy-like flowers that appear in flowerheads. They are characterized by a unique, unpleasant odor. They are tough plants able to withstand many adverse conditions. This trait made them problematic non-native weeds in the environment and agriculture, additionally due to the potential to cause skin irritation. The genus was named in the honor of the German botanist Manfred Dittrich.
