Nothoscordum bivalve is a species of flowering plant in the Amaryllidaceae known by the common names crowpoison and false garlic.

It is native to the eastern United States from Texas to Florida up to Nebraska and Ohio, as well as Mexico, Peru, Uruguay, northeastern Argentina and central Chile.

[2][3] Nothoscordum bivalve is a perennial herb growing from a bulb about a centimeter wide.

It is a favorite nectar source for small butterflies such as the falcate orangetip.

It has been observed to be nyctinastic, or closing at night, which contributes to its mechanical self pollination.
