Stinknet or globe chamomile or Oncosiphon piluliferum

This is an invasive plant from South Africa that landed in California about 1981. It has a strong smell and even goats don't want to eat it.
In January 2024 this plant was indicated as a noxious weed in Arizona. It has taken over many places that use to be the habitat of natural wildflowers in Arizona. This causes stress on the native pollinator animals that rely upon the native plants for pollen and food.
When they dry up in the summer it creates large quantities of tinder that allows wildfires to increase in intensity and frequency. Those fires are devastating to native plants like the iconic Saguaro.
