Description

Zigadenus glaberrimus is the only species to remain intact in the Zigadenus genus.  Twenty species formerly in the genus Zigadenus are now found in four different genera.  Distinguishing characteristics of Zigadenus glaberrimus are the rhizome, which is thick and twisted and two conspicuous glands per tepal.  Former members of the genus grow from a true bulb.

Large Death Camus is a short-lived native perennial wildflower with large showy white flowers.  The panicles boast 30 to 70 blooms.   

In its native environment, it can be found growing in sandhill seepage bogs, pine savannas, pocosin edges, along small streams and in sandy pine lands.  Typically, it grows in areas of low elevations, under 350'.   

Insects, Diseases, and Other Plant Problems:  All parts of this plant are poisonous to both humans and animals.  It contains toxic alkaloids.  Dried seed and capsules are most toxic.
