I can't seem to find much information on this bulb which is not tall - maybe 6 inches or so, with large white flowers on several stems. Just a very nice plant and it doesn't seem to multiply very rapidly or even set seed although I'm so mean to it that it's not a surprise.
Can anyone help me on this?

The narrow leaves and the name "comosum" suggest it's close to Ornithogalum fimbriatum, which is not invasive for me. These short-stemmed "thogs" can be invasive, depending on species, though. I enjoy O. orthophyllum in the bulb lawn, where it seeds mildly and stars the grass attractively in late spring. The various species I grow flower from midwinter (starting with O. lanceolatum) into July (O. ponticum, O. magnum). My gem is O. reverchonii, which is hardy outdoors here despite its coastal origin.
