Jay, you get the gold star. It is Indigo hirsuta aka rough hairy indigo. It's invasive here. Well, it's there & by all accounts I can't get rid of it sooooo.... I & the flutterbys & the hummingbirds may as well enjoy it.
Hey, thanks for the link. I had no idea the Scrub jay trail started here in Lake City where we've just moved to. Will have to check it out sometime. We used to have Scrub jays at our house in Martin County until the Blue jays ran them off.
