[edit] Remarks

Includes Hoary cress or Whitetop, C. draba (L.) Desv., Hairy Whitetop, C. pubescens (C.A. Meyer) Jarmolenko, and Lenspod Whitetop, C. chalepensis (L.) Hand-Maz., all of which occur in AB according to USDA Plants. Not especially competitive in established communities, but can spread underground like Creeping Thistle and be very persistent. Cutting or herbicide are most effective when plants are in full flower, and relatively ineffective prior to that stage.
