Blossoming from April to October, trailing allionia, known in some
places as “trailing four o’clock” or “windmills,” is a spreading annual
with small but colorful blossoms on long, trailing stems. The prostrate
branches are sticky, so are often covered with grains of sand and flecks
of mica. What appears to be one blossom is actually three flowers,
giving it the name “pink three-flower.” It is found on dry, sandy
benches throughout desert regions of the Southwest. Fruits are winged.
