Weed Watcher Workshop

April 24, 6-8 pm, Tualatin Soil & Water Conservation Office, 7175 NE Evergreen Parkway, Suite #400, Hillsboro, RSVP here online.

A patch of Lesser Celandine is choking out
the spring lilies in this garden.

April 30, 6-8 pm, PCC Rock Creek Campus, Building 2, room 110, RSVP here online.

Cedar Mill has seen a true invasion this year of the invasive weed Lesser Celandine. This cute but highly invasive weed is popping up everywhere this spring, from neglected corners to well-cared-for gardens. It’s extremely difficult to eradicate because its roots tend to break off when it’s pulled, and will sprout new plants next year. It also turns out to be poisonous to animals and people. You can find out more in this article from the Clackamas SWCD, and you can also go to one of these Weed Watcher Workshops.

Weed Watcher workshops are presented annually in the spring to help alert area residents to the Class A weeds. Each workshop consists of an introduction to invasive species control, a walk-through of the weeds of greatest concern, and time to practice identifying these plants with live samples. Participants receive a copy of our handy weed ID guide, which includes information on how and where to report infestations. Bring in your mystery plant for identification.

During the workshops, weed experts explain why not all weeds are invasive. In order to be considered an invasive species, these weeds have to be more than simply unwanted. If an unwanted weed rapidly infests an area and has a negative impact on human health, economic productivity, or the surrounding environment, then Weed Watchers should be on the lookout in order to catch the invasive species before it establishes itself and the population explodes.
