General Poisoning Notes: Blue flag (Iris versicolor) is a native herb found in eastern and central Canada. This plant has been mentioned as causing poisoning in humans and animals, but case reports have not been found. The plant juice can cause dermatitis in sensitive individuals. glycoside, iridin (or irisin), has been implicated as the toxic compound in iris species, although this has not been confirmed (Fyles 1920, Cooper and Johnson 1984).
We have loads of deer around here & the only time they have ever tried my iris is first thing in the spring, when the irises are just starting leaves & almost the only new green thing in sight. Besides daffodil leaves, which are toxic. As it is just a bite or two here & there, I don't mind that much.he deer do not like rhizome at all, but they will eat the leaves. Unfortunately they sometimes yank the rhizome out of the ground, eat the leaves and spit the rhizome...wherever! It is usually in one piece with no bites, but I find it laying in a strange bed, nameless and lost.
