Invasive Phenology Update: Multiflora Rose, Canada Thistle, Poison Hemlock, and Chickweed

There are a lot of plants coming up, too many to document.  Here a few I found the other day.


Poison hemlock (Conium maculatum) – basal rosettes


multiflora rose (Rosa multiflora) – leaf out


Canada thistle (Cirsium arvense) – emergence


Chickweed (Stellaria media) – flowering
