from a wildflower seed pack at HD
pretty much evergreen in my area with blue flowers all summer
It looks like blue flax to me. (Linium perenne lewissii)
If the blooms last only a day each and then drop the petals all over the ground, thats probably what it is. Its not a true perennial for me. It usually lasts a couple years and then sort of wears out. It blooms fairly early in spring.
Its common to find it in a wildflower mix.
