It's scientific name is Caryopteris clandonensis. It is in the Verbenaceae family. According to the "Southern Living Garden Book", it is an Asian native and is valued for their contribution of cool blue color to flower borders from mid-summer to frost.
I was attracted to its delicateness and the blue color. As many times as I've been in Sawgrass Lake Park, I don't remember ever seeing it before. It must've been planted by the birds.
