Knapweed Update

Day 261: Update: I have heard back from the King County Weed Board. Bighead Knapweed is regulated and they've forwarded my letter to the WSDA Nursery Inspection Program. They advise, "They are the agency that regulates the quarantine laws of the state and I think this would fall under that. Bighead knapweed is sometimes sold as a cut flower by market flower vendors so it’s possible that is the source for the restaurant. The flower growers often get the seeds online and don’t know the state quarantine law. We sometimes find flower growers in King County growing it in the farms and have to explain the law to them."
