About

Toxicoscordion paniculatum is a species of flowering plant known by the common names foothill deathcamas, panicled death-camas, and sand-corn. It is widely distributed across much of the western United States, especially in the mountains and deserts of the Great Basin region west of the Rocky Mountains. It grows in many types of habitats, including sagebrush plateau, grasslands, forests, and woodlands.

Where it grows

Toxicoscordion paniculatum grows in every state of the contiguous United States from the Rocky Mountains westward and into northern Mexico. In the United States it found almost entirely west of the Rocky Mountains in Colorado and New Mexico, while growing in a few scattered, isolated populations in Montana. To the west the foothill death camas grows in every county of Utah and Nevada while mainly growing in the southern portion of Idaho. It is found in the drier eastern areas of both Washington state and Oregon. In California it is found widely north of San Francisco Bay in inland areas of the Northern Coast Ranges and the Klamath Mountains and is found in the Sierra Nevadas from the north to the southern end of the range. It is only found in the northern parts of Arizona. In Mexico it grows in the states of Chihuahua and Sonora.
