These were mystery bulbs I found along side a creek in raliegh nc. After they bloomed I was able to identify as Star Of Bethlehem - Ornithogalum Umbellatum -. They were easy to transport and seem to be pretty hardy here.

They say that Ornithogalum can get pretty aggressive.

Thank you much 4 info. I've been learning so much from Google and beautiful books I've bought from thrift stores (where I paid 1$ for!!) I did notice that they were abunded where I found them like they spread easily. I found these bulbs along side 3 different creeks that were within a mile of each other. I'm hoping I won't have a problem here because my home is on dry red compacted soil. However I'll be sure to now take precautions. Thank you again for taking the time to share with me. I always am glad to receive advice and information.

I've found them to spread throughout my garden, however they're pretty unobtrusive when not in bloom and I don't (yet) consider them invasive. They add such sweet flowers in the fairly early spring and then they just look a bit like weirdish grassy clumps. I just have to remember not to weed them out, think they're something else (blue-eyed grass, muscari....)

You don't have to worry about accidentally weeding them out because you can never get rid of them that way. They will always leave little bulblets behind to haunt you unless this is what you really want to grow. They will crowd out and cover over other bulbs (in my case lilies). This is what jmorth means when they say they are aggressive. It won't happen overnight but the day will come...

I started out with one bulb and now they are massed along the back of the house, pretty much keeping me from using that real estate for other plants that I would like to grow.

I say, if you really like them keep them in a container and DEADHEAD as soon as bloom is finished.

I bought a Black Gamecock Iris once and it turned out to be one of these. They grow all over the yard now. I don't go after them often enough but now they have colonized in the middle of other plants, especially the Hakonechloa and it wins.

Thanks for the words of advice. I'm gonna put mine in a wood box, away from everything else. I accidentally mixed them with other bulbs but have been weeding them out to put in separate spot.
