Some plants in the aster family have developed colored bracts that become dry, and persist long after they've done their job attracting pollinators. Now they attract us and wind up in gardens and flower arrangements. This version of a 'strawflower' is our native pearly everlasting. The heads are each close to a half inch across. The actual flowers are the yellow bits in the centers. Each of those tiny projections is a pistil of an individual flower. In this species, pistils and stamens are on different plants.
