Both species are established feral plants here in the greater Washington,
D.C. area. 

Of the two, O. umbellatum is the more commonly encountered. This species
does not seem to set viable seed - at any rate, I've never known it to do
so. But every scrap of living bulb seems endowed with an inalienable right
to near immortality.

Ornithogalum nutans, although less frequently encountered, sets viable seed.
A feral clump I have observed off and on for decades has not spread much at
all. It has also been my experience that bulbs of this species do not
respond well to drying.
