This is from the Red Butte Garden, Utah. Small patch of perennial plants. Five-petal flowers in a head surrounded by the involucre - Asteraceae or Dipsacaceae (anything else?). The anthers are separate which does not favor Asteraceae. Flowers are radially-symmetric which is not in favor of Dipsacaceae. The leaves are linear, the stem looks scapose, hairy. The short pedicel on the top of it, however, seems to be of different texture. Any ideas what this could be?
