Summary

Nothoscordum bivalve, commonly known as Crowpoison, is a deciduous perennial herb that is native to subtropical and temperate America. It typically grows from a small bulb approximately one centimeter in diameter and produces one, sometimes two, erect stems reaching up to 40 centimeters (16 inches) in height. Crowpoison is notable for its spring-blooming flowers, which are star-shaped and come in shades of yellow, white, and orange, although they lack fragrance. The plant’s fruit is a capsule, which is less commonly observed in garden settings.

Crowpoison is valued for its ability to attract small butterflies, such as the falcate orangetip, making it a beneficial addition to pollinator gardens. It thrives in partial shade, requiring medium amounts of water and well-drained soils. While it is not commonly used in large-scale landscaping, it can be an attractive addition to wildflower meadows or naturalized areas where its low maintenance and ability to naturalize are advantageous. Gardeners should be aware that despite its common name, Crowpoison is not poisonous to crows or other birds. However, all parts of the plant are toxic to humans and pets if ingested.CC BY-SA 4.0
