Is this a relative to Queen Anne’s lace, grown on dry, sandy soil?
no, this is not related to Queen Anne’s lace, which has flat-topped flower clusters. It is, though, a very interesting and attractive native plant that only grows in the sandhill region, called Polygonella americana, the southern jointweed. It can be locally common, but the range is limited by its soil preference. More technical information can be found here: http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242417023
