Other info. - This species is uncommon, only sporadically escaping cultivation. Large patches can be quite showy. In Missouri it is not truly naturalized, as populations do not seem to persist. The plant is edible, with a flavor similar to garlic, and it is frequently used in Asian cuisines.

The familial classification of the genus Allium is controversial, with some authors segregating it into Amaryllidaceae or Alliaceae.
