Oenothera deltoides, also known as Birdcage Primrose or Dune Primrose, is a desert plant with large, white, papery thin flowers.
Description
The plant is grayish with basal and deltoid shaped leaves. The flowers turn pinkish as they mature. The plants thrive in desert areas of the Southwestern United States in sandy areas. When the plants die, the stems curl upward and form the "birdcage" for which the common name is derived.
This annual plant flowers in April and May in the Mojave and Colorado deserts.
