Cinder phacelia (Phacelia serrata) grows on exposed cinder slopes and is dependent on having volcanic cinders as a substrate. The plant is usually between 4-14 inches tall and grows at elevations from 5,200 to 8,000 feet. The upper leaves are attached directly to the base without a stalk, and in August through September it has a blue/violet flower. This plant is only found in two locations in the United States; El Malpais National Monument and Sunset Crater National Monument in Arizona.
