Notes
Flora of North America recognizes forty varieties of E. umbellatum, all native to the western U.S. Six of those varieties are native to Colorado. Varieties ramulosum, majas, aureum and umbellatum have been documented in Larimer County. Variety subaridum is found in southwestern Colorado and variety porteri is found at higher elevations on both the east and west slope. All the varieties vary slightly in growth habit, flower color and pubescence.
This is an important larval and adult food host for many of our native invertebrates.
Great for rock gardens.
