  No, tansy ragwort is toxic. It poisons the liver. It’s also very bitter so not something you would want to eat anyways. Thanks for asking!

Have you ever wondered why in autumn green spaces fill up with these unique circular plant shapes? 🧐Look no further! Swipe to learn about the wonder of rosettes🥬.

Meet Skye (she/her)…oh wait that’s me! 👋 Hi all, I wanted to introduce myself as the new admin for this page as the King County Noxious Weed Control Program’s education specialist! I hope to use this page as an open space for learning and asking questions about weeds, particularly those in Western WA.

Touch-me-nots got you confused? Also called jewelweed, these two large species of Impatiens were introduced to the Pacific Northwest by gardeners who meant well, but opened a Pandora’s box of problems for native plants and habitat on creeks and dappled woodlands in our region. The orange flowered one, spotted jewelweed, is highly beneficial in the eastern United States where it is native and provides food for hummingbirds. The pink-purple one, called policeman’s helmet or Himalayan balsam, is a delightful plant in its native range in India. However, in our neck of the woods, both species can overwhelm creek side plants and create dense monocultures that don’t provide the same habitat diversity as the native plants they replace. Policeman’s helmet is especially problematic because it’s so tall that it can reduce shrub layer species that do a better job reducing erosion. Policeman’s helmet, the purple one, is a regulated noxious weed in King County because it’s limited enough that we can hope to contain it. Please let us know if you see it, report online through our website link in bio. Spotted jewelweed is not regulated because it is too widespread and also it can be confused with some native orange jewelweeds, so get an expert ID before removing it to avoid pulling native plants out by mistake.

Chop it and bag it! Tansy ragwort in seed means at least 15 more years of new plants! It’s toxic to livestock, it spreads like crazy, it makes a zillion seeds that blow far and wide, and it’s a Class B noxious weed in Washington. Your neighbors will thank you if you keep it from spreading and so will we! Video and demo by Tom Erler. #bagitup #tansyragwort #weedcontrol #stopitbeforeitstoolate #toxicplants
