Since the Texans scored their last touchdown, animaux saw fit to opine:

I didn't finish reading your whole post, but the only hot weather turf
we have
for shade is St. Augustine. Rye, perennial or annual, or fescue, tall
or
otherwise will melt off in summer at the temperatures rise. The best
way to green things up under trees is to either use the very time
consuming turf in the form of sod, or look into native ground covers
which will do well in shade.

We used tall fescue, had to seed it about 3 years running, but once it
got thick enough it quit burning off in the heat.

Only in the shaded areas, though - Bermuda (yek) and St. Augustine
elsewhere.
