Plant Profile: Zigadenus

Zigadenus is a genus of flowering plants that currently includes just one species, Zigadenus glaberrimus, commonly known as the sand bog death camas. This plant thrives in pine bogs, savannas, and sandy pine areas across several U.S. states, including Alabama, Florida, Georgia, Mississippi, Virginia, North Carolina, and South Carolina.

Emerging from thick, twisted rhizomes, it produces flowers from mid-summer to early fall, showcasing white to creamy hues.

Death camas contains various steroidal alkaloids akin to those found in Veratrum (false hellebore). The bulb and mature leaves are particularly toxic, with the alkaloids exhibiting strong hypotensive effects. All parts of the Mountain Death Camas are poisonous, possessing alkaloids that are more toxic than strychnine, posing a risk to livestock. The plant survives winter as a bulb that closely resembles wild onion.

While this plant is generally not available for commercial sale, its ability to proliferate in the wild and form extensive stands makes it quite appealing.
