Plant Lore:
This plant is almost as deadly as it is beautiful. The leaves have a high concentration of irisin, which is a chemical that is poisonous to livestock and people alike. Symptoms can become as extreme as to include severe and simultaneous vomiting and diarrhea.

When and where to see at Bryce:
This flower can be found in large groups in open, moist grassy meadows at the lower elevations of the park and surrounding countryside. In drought years, try the area around the nearby Tropic Reservoir.
