Diamonds are a girl's best pollination syndrome

Goldenrods are a slightly smaller but more persistent example of this approach to reproduction. Cross pollination is most effective for insuring the health of a species. There's more variation and adaptability that way. Goldenrods, asters, and some other members of the family seem to be more persistent in that effort. Their tiny points come apart and curl back later, or not at all. This is roughleaf goldenrod, Solidago patula.
