Antelope bitterbrush or Purshia tridentata is a very important food source for Deer, Elk and of course Antelope during the winter months. The flowers turn into fruits that are very bitter when tasted but sustain many species of animals in the high deserts of the intermountain west.
The name tridentata derives from the three-lobe tips on the foliage of this plant. This one will soon be setting fruits for the winter. Oh and check out the little bug in the middle of the flowers.
