Thank you for this report, Jim.

Unfortunately, now that community members are becoming aware of this plant we are finding it and receiving reports of it all over the City of Hood River - often in sites like this one (a residential landscape setting). We really appreciate these reports because it helps us document the scope of the infestation. No control efforts have been found to be very effective. However, if this is your property or that of a friend, and there are only a few stems, it may be possible to dig this small patch out if it is done carefully and all tubers and stems are removed and bagged for disposal. Please wear gloves as many people have reported having poison oak-like symptoms from touching the sap of this plant.

Again, thanks for your report and sharp eyes!
