Ornithogalum. Star of Bethlehem. Around here, it's a weedy pest.

Yes, in your zone it reseeds & the bulbs multiply like mad.

Thanks, I thought I remembered seeing it online somewhere but didn't know what it was. I don't know about reseeding- it was the only one there. Maybe the heat makes it behave? I will keep it in a pot just in case. It's nice in a quiet way I think.

Yes, it does reseed prolifically. From a handful of bulbs about 30 years ago, I now have thousands, mainly in my lawn. Herbicides don't even take it out. But, I don't mind. It's pretty, hardy, and nothing phases it.

This is the worst pest known to man-for heaven's sake don't let it get in your flower beds.

Is this plant the same thing as a rain lily?

run. run far.

I'm still trying to get rid of this, from a single volunteer.

Rain lily is Zephyranthes, not the same thing.
