Notes
Flora of North America recognizes four varieties of R. hirta, all native to the U.S. Variety angustifolia is native to the southern states; variety hirta is native to the eastern states and floridana is only found in Florida. Our native variety pulcherrima, can is native throughout most of the U.S.
This is an important larval and adult food host for many of our native invertebrates.
