Ornithogalum - weedy?

Yes, Jim, I liked those two pages. Nice big print, clear
information, and lovely pictures, better than most sites that are
trying to sell the bulbs.

About umbellatum it says: Cultivated and escaped into open fields,
waste ground, parks, open woods, roadsides, railroads.

I assume people in your area behave similarly to those here. Those
bulbs didn't leap out of the garden on their own and colonize waste
ground. Instead, people weeded their garden and trundled the weeds
to the nearest public space where they dumped the wheelbarrow full of
whatever they didn't want. That gave the weedy bulbs their start.
