Here in San Antonio, I have found this plant useful for lining the edges of my garden path and I believe it can be used in a rock garden setting. I transplanted my plants from unirrigated lawns.
Over the years, I observed this to grow well in very poor, heavy clay soil where it survives lengthy droughts and periods of being in soggy poorly drained soil. Mine bloom twice a year, in late winter when irises bloom and in late autumn.

At present, my only reservations about this plant is its small size which makes its beauty fully appreciated only at close range and best if growing in large clumps, and as yet, I have not grown it long enough to determine whether it will prove weedy.

I have these growing in my yard and they multiply very fast and like unwanted wild onion grasses, they are hard to get out of perennial beds due to the fact that you must get the complete root and if you miss a little piece it will regrow just like a real onion or garlic grass. What i like about these though is their beautiful white intracate wild flowers that bloom beautifully when their leaves start to turn silvery and they look great in contrast with tulip bulbs, sweet iris, and rock flowers like creeping phlox and also daffodils, that all bloom early-mid to mid season spring, even though this wildflower is invasive and poisonous to eat it is still beautiful..peace..mike

Comming originaly from a region where this plant does not grow, I was pleasantly surprised to notice it growing in just about every yard and grassy area in Houston. While this may make it a weed to some people's minds I find it to be an attractive little addition to the local flora. The foliage is grassy so it blends in well with most localy grown grasses leaving the flower stalks to make a nice desplay scattared throughout the field or yard.
I have had luck transplanting the bulbs into small pots where they looked quite attractive as a small accent plant on a stand on my patio. While the flowers last for some time, the plant dies down after the seeds ripen. The weather of Houston seems to interrupt the plants growth with the summer heat causing its dormancy after spring ... read more

This plant is also called "False Garlic." It looks like wild onion or wild garlic but has fewer and larger flowers and lacks the distinctive onion odor.
