Remarks

Attractive yellow Snapdragons. Less common than Canada Thistle or Leafy Spurge, but with similar patch-forming propensities. The scientific naming of this species and of common toadflax is confusing. After looking into it, Dr. Peter Achuff said "... the consensus seems to be that Dalmatian toadflax is L. genistifolia ssp. dalmatica and common toadflax is L. vulgaris, with a synonym of L. angustifolia. I think that's the way the yet-unpublished Flora of North America account will handle it."

It is being targeted with Mecinus janthinus – a stem boring weevil from the Agriculture and Agri-Food Canada Lethbridge Research Station.
