Zigadenus Glaucus is a flowering plant commonly known as the ball-head waterleaf. However, there are other synonyms for this plant. It is also known as the meadow deathcamas, death camas, and wild onion. Death camas is derived from the fact that the plant contains highly toxic alkaloids that can cause grazing animals to die. On the other hand, the name wild onion is used because its bulb has an onion-like taste and smell. Besides these synonyms, this plant is also commonly referred to as glaucus deathcamas and foothill deathcamas. Regardless of the name, it is important to note that the plant is toxic and should be avoided.
