Datura inoxia, Datura wrightii, or Brugmansia. I haven't found them to be
"very
"xeric" and are very heavy feeders.

There is a big difference between Datura and Brugmansia. Datura grows wild here
in Colorado out on the plains with no supplemental water or fertilization. It
is a feature in the xeriscape prairie garden at Denver Botanical Gardens where
it also receives no supplemental water or feeding and seems to thrive, even in
our drought.

I've been growing and collecting datura and brugmansia for a decade. D.inoxia,
D.wrightii are not xeric, they are also not native. D.stramonium is xeric and
native, but it does not have the showy flowers lf .Wrightii and .inoxia.

Brugmansia are native to the Andes.

I think I know.
