Submitter does not have a specimen

Thanks for posting as posts help us understand the spread of these species through out the county. Unfortunately without a picture I can neither confirm nor deny if you are correct. However you are likely correct as tansy is widespread through out the county. Due to it's prevalence, we do not have the resources to treat tansy. If you are able to gain access to the property here are our best management practices for controlling this plant.
