Datura? :-)

IIRC, if they are pointing downwards, they are brugmansia, if they
point upwards, they are datura.

I've found huuuuuuuggggeee brugmansia trees in quite a few places
here on Oahu. No dying back so they just keep growing and growing

Sounds lovely, thanks for the plant lesson! :-)
I'm always up for an education...

Do they have similar alkaloids?

Yep. Here's one of my Daturas. This one is several years old. By the
end of the summer it has spread to about 10 feet in diameter. Late in
the summer I pluck at least 20 spent flowers from this plant alone
(sometimes 50-60) each evening in order to prevent seed pod formation
and promote blooming. I have been trying to get night pictures of
hawkmoths feeding on my Daturas, which has proven to be a maddening
exercise in futility.
