Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Small companion mammals (rabbits, guinea pigs, hamsters): No known toxic effects; very excessive consumption may cause mild, temporary digestive upset

Pet and wild birds: No reported adverse reactions from ingestion of small quantities of Star Lily

Commercial livestock (cattle, sheep, goats): Classified as non-toxic, no negative effects noted from normal grazing exposure

Confusion Risk

The following plants look similar and may be confused:

Death Camas Zigadenus venenosus

Both produce star-shaped white spring blooms; Death Camas has narrow, grass-like leaves and is highly toxic to all mammals, unlike the harmless Star Lily

White Camas Anticlea elegans

Similar lily-like white flower clusters; White Camas contains toxic steroidal alkaloids that cause severe poisoning, a key difference from non-toxic Star Lily
