Notes

Flora of North America recognizes four varieties of P. pumila, all native to the U.S. Varieties susquehanae, depressa and pumila are found in the northeastern states. Variety besseyi is found in most of the midwestern and western states, including Colorado. In Larimer County, this plant appears to be rare in the wild. Only three current populations have been documented, all occurring on City of Fort Collins Natural Areas.

This is an important larval and adult food host for many of our native invertebrates.

This plant is not deer or rabbit tolerant.
