The predominant plants growing in Florida dunes are sea oats. They have an extensive horizontal root system which stabilizes the dunes and keeps them intact during storms. This is why it is illegal to disturb or pick them. In the background is the Sandestin Beach Club, a very classy establishment. Looks nice on black.
Very inviting... especially for those of us further north. :) I like your POV and the details of the grasses in the foreground, against that lovely blue sky.
