Prince's plume: Stanleya pinnata, Brassicaceae (mustard family)

This is a festive plant if I ever saw one. And the first time I did, I thought it was regular tansy mustard on steroids. Not surprising since it's in the same family, and smells a lot like kale. The plant is enormous, considering the typical low profile of desert dwellers—this one is about my height. 

According to some resources, it is edible, both leaves and showy yellow seed pods, but the plant also soaks up a sizeable amount of selenium from the earth, so is labeled toxic in other circles. Everyone is entitled to their own opinion...but...climate change is real!!!
