This bright yellow flowering plant, Senecio jacobaea, or Tansy ragwort, is an invasive, toxic, noxious weed that is very harmful to any animals that eat it. It's definitely a plant out of place, as it's so pretty.
Unit 5, starting to seed
I think this is an invasive weed growing in the middle of an old logging road.
This old logging road on prospect ridge was destroyed for hiking and straw was brought in to reduce erosion but it brought it lots of weeds too. How ironic.
I wish they would turn these old roads into trails instead of digging them up and making them difficult to hike
Large, showy flowers for a ragwort (close to 1" [2 cm] across), conspicuous in these tight clusters atop tall, narrow roadside plants (~3-4' [1+ m] hi).
