In The Garden: Unlabeled flower

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?

 

If it were in Britain I would say Armeria maritima...

Armeria maritima for me too, unless there's other similar species of Armeria there.

 

Thank you, Silver and Michael, that's it!
Armeria maritima is listed as native in some states, including neighboring Colorado. No other species of Armeria mentioned.
None of Plumbaginaceae species occur in Utah, so I missed the whole family.
