Gloriosa daisy is an annual or short-lived perennial flower. In August, sturdy stems bear large daisy-like flowers. Each bloom has a dark brown center and is surrounded by wide petals that range in color from yellow to orange to brown. The leaves form a low dense mound.
This plant is a nice performer at the Xeriscape Demonstration Garden. Individual plants die after one or two years, but new seedling appear to replace the original plants.
This is a short-lived perennial, so it is a good idea to leave the seedhead in place to encourage volunteer seedlings. Remove the last season's growth in early spring.
