Ornithogalum nutans - weedy?

Diane Whitehead asked,
Ten years ago someone gave me a few
little bulbs of O. nutans and I put them in a pot. I have just
removed them from the pot, to plant in the garden and there are a LOT
more bulbs than I started with. Now I am concerned that nutans may
prove to be as unacceptably prolific as umbellatum.
I've heard that O. nutans is invasive in some European gardens, but I've
been growing it here in Oregon for about 15 years (received from a seed
exchange under the misnomer O. arcuatum) and it has not spread at all. It
may be better-behaved in a summer-dry climate. On the other hand, I also
grow O. umbellatum, naturalized in rough grass and not watered in summer,
and it has never appeared anywhere else either.
