I'll check out the awning option - great idea. The sun's so high in the summer they wouldn't need to be deep at all.
The previous owners ruled out trees by planting hundreds of sq ft of concrete topped with crumbling fragile coolcrete. But for the lack of soil what I'd really wish for are trellises covered moonflowers, passion flowers, and all sorts of fast growing beautiful vines. Maybe I still could do this with long rows of planters. Thank you for the excellent suggestions. You also get a brewski/coffee if you're every by Largo/Sarasota FL, email in profile.
