Arizona lupine is a common early spring ephemeral wildflower of the Colorado Desert. The purple-pink flowers show a yellow spot on the upper petal, which changes in color to red once the flower has been pollinated to discourage insects from visiting it after pollination. This photo shows both red and yellow petals. Anza Borrego Desert State Park.
