Greasewood

I've called it Greasewood most of my life. Many call it Creosote Bush. It's larea tridentata. It may be the most common plant on the deserts of the U.S. Southwest.
The little whitish things you might be able to see growing on it remind some of pussywillows.
The fuzzy little things show up after the blossoming of Greasewood's little deep yellow flowers.
