Hawkweed Identification Guide (Montana State University Extension)

An excellent guide for hawkweed identification was developed by Peter Rice, University of Montana and John Halpop, Montana State University Cooperative Extension Service. Since exotic and native hawkweeds share some similar characteristics, the guide provides useful diagnostic tips for separating orange hawkweed and two yellow-flowered exotics from four native hawkweeds. The guide ‘Hawkweed Identification’ is available on-line at http://msuextension.org/publications/AgandNaturalResources/EB0187.pdf or by contacting Montana State University Extension Publications at:
