>> These are about 3yrs old so they've got pretty good sized trunks on them
Ohhhhh! Perennials. Got it.
>> I've got them on the west side of the greenhouse so they don't get the direct sun except for a few hours in the afternoon but that's enough to make the things droop terribly.
Texas is SO unlike anywhere I've ever lived. My first clue that "Zone 8 Texas" is nothing like "Zone 8 Seattle" came when someone mentioned that all his early tomatoes were dying from the heat and about to expire. I read that at a time when I was carrying my only tomato seedlings in and out of the house each day so they didn't get so chilly at night they would start hibernating. I think I put mine IN the ground several weeks after the Texas Tomato guy pulled his OUT.
When I see "needs full sun", I usually think "Bummer. I don't have really FULL sun anywhere, even in my least shady spots!"
I guess you see that and think: "ONLY full sun?? I'd better give it some shade so it doesn't catch fire!"
