Fringe Cup Allionia Linearis
The purple flowers of the Fringe Cup open late in the afternoon and wither as they close in the heat of the sun the next morning. As with most red and blue flowers, albino forms are sometimes found. The plants are 2-5 ft. in height and may be found in bloom all summer on prairies, foothills and gravel-slides at 4000-9000 ft.
