Thanks, Fermi.
That looks like a good I.D.
I've never bought seeds of a drimia, but back in 2006 I picked a few seeds from
an ornithogalum-like plant near Clanwilliam. After ten years, I can't remember
clearly what the flower looked like. The seeds never germinated that I noticed,
so I emptied the pot into my "no-show" area, near where this plant has appeared.
