Notes

Flora of North America recognizes four varieties of R. laciniata, all native to the U.S. Variety bipinnata is native to the northeastern states; variety digitata is native to the southeastern states and variety heterophylla can only be found in Florida. Our native variety ampla, is found throughout the Rocky Mountain States.


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