Pregnant Onion (Ornithogalum longibracteatum)

Here is a picture of my pregnant onion about to bloom. I've grown this one from a baby - it's about 3.5 years old. It gets a lot of morning / afternoon sun - a South East exposure. It's made 5 babies so far - hopefully more to come!

I have 2 babies ,didn't know they bloom.....

Florence, OR

These are fun plants, mine has been living outside in a pot for 4yrs or so, and the pot is exploding with babies. I live on the Oregon coast so temps. are generally mild....

I have had these for about 6 years now. They withstand dry conditions-I bought it at a cactus show-but seem to much prefer average moisture. Just last weekend I found the latin name and did a web search, finding this thread amongst other information. There is a lot of inconsistent data out there. The species name is also reported as cordatum. Along with Pregnant Onion, it is also called Desert onion, Healing onion, Sea onion or False sea onion. There are reports of its use as an anti-burn agent, like Aloe. The sap is, I suspect, where it gets its genus name, 'bird's milk'.

Mine flowers annually, and has produced a whole bunch of offspring. After flowering, they seem to tip to one side, perhaps from the weight of the long stalk. Quite an amazing plant.

hey dave when an onoin plant blooms what do u do when the flower dies? do u remove the whole stem or will it just die off? i've had mine about 3 years now. it is already blooming and i have gotten about 10 babies off of it. i just don't know if i remove the stem after the bloom dies or what. thank you

I have always just cut the stem off when it is done blooming. This summer, mine bloomed 4 times, and by the end of the season, I got really tired of 4' long stems coming out of the plant! I found that once you cut the stem off, the remainder will wither away and you can eventually just pick it off.
