I've grown some pretty white flowers in the greenhouse that only
open at night. This is probably something that some folks in the
PBS are quite familiar with but it's new one for me.

My guess is Hesperantha cucullata. Bring it indoors and see if it
fills your house with fragrance. I once found three or four
differently labeled seeds from seed exchanges once they bloomed were
all this plant. Most, but not all were very fragrant at night. No
fragrance during the day however.
