Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Horse: Toxicity is unconfirmed; no clinical data on ingestion effects exists, so precautionary access restriction is advised
Small companion mammals (rabbits, guinea pigs): No confirmed toxicity data available; ingestion of small quantities is unlikely to cause adverse effects
Confusion Risk

The following plants look similar and may be confused:

Belladonna Lily Amaryllis belladonna
Visually similar for their shared pale lily-like flowers and low-growing habit; key difference: Belladonna Lily has broader leaves and is highly toxic to all companion animals
Wild Daffodil Narcissus pseudonarcissus
Similar upright flowering growth pattern; key difference: Daffodils have a distinct trumpet-shaped central corona and contain toxic lycorine that causes severe gastrointestinal distress
