Solidago sempervirens where the Fern Valley main path meets Crabtree Road

This is a cool goldenrod with a lot going for it. The flowers are attractive and pretty typical for Solidago, maybe a bit larger, but the ripened seedheads are spectacular, even better with a little frost. And the clumping basal foliage is persistent well into the winter. Hence sempervirens I assume. It's a dune dweller with a huge range that includes the Atlantic and Gulf coasts. There are two varieties, basically a northern and a southern. This is one of the Solidago's I grow in Adelphi.
