Bulley's iris is similar to most other plants of its genus in that it contains moderately toxic properties in most parts of the plant, namely the leaves and rhizome. Species in the Iris family contain a whole host of different toxins, including irisin, iridin, irisine, and pentacylic terpenoids. It's no wonder they're harmful when ingested! Poisoning typically occurs through accidental ingestion, particularly in children who like the looks of the bright blue flowers! Ingestion can result in a high temperature, extreme tiredness, nausea, vomiting, diarrhoea, and excessive salivation. Bulley's iris is also harmful when touched directly, causing skin irritation or allergic reaction.
