Spring’s flowers’ shining faces turn toward the sun.
We have since learned that the mystery pink flower is Streptanthus maculatus, a clasping jewelflower. This member of the mustard family grows in the Arkansas Ouachitas. According to USDA, it also grows one county in eastern Texas, but that’s disputed here: http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250094989. It also grows in parts of Oklahoma. (its Arkansas range is pictured here: http://plants.usda.gov/java/county?state_name=Arkansas&statefips=05&symbol=STMA2)
