Fleeceflower Groundcover

Asked September 6, 2017, 11:38 AM EDT

I planted a common groundcover called Fleeceflower back in the 1980's. It is still doing well and I know it can spread by the roots, my bed is in a confined area and hasn't been a problem. A new neighbor insists that this is on the MN Specially Regulated Plant list and I need to get rid of it. I looked on line and the Fleeceflower that is listed on the MN Specially Regulated Plant list is the Cuspidatum and Sachalinense varieties. I think the variety I have is Fallopia Japonica. It gets a small pink flower and is about 18" to 24" high. Do you know if the fleecefower that was sold commercially back in the 1980's and 1990's is on any MN lists and should be eradicated? Thanks Alan

Thank you for your question.

Hard to say what garden centers were selling in the 80's. Our suggestion would be that you contact the Minnesota Department of Agriculture Arrest.the.Pest program by emailing Arrest.the.Pest@state.mn.us or by calling (888) 545-6684.

Hope this helps.

Forget about the 1980's comment. I gave you the name of the fleecflower I planted and the one's listed on the MN Specially Regulated Plant List. Guess you don't know anything about Fleeceflower plants.

Thank you for your feedback!!

Again, please contact the MN Dept. of Ag at the provided email address or phone number.

Fallopia japonica (AKA Japanese knotweed, Mexican bamboo and Japanese fleeceflower) grows 6-9 feet tall. However a dwarf cultivar (Fallopia japonica var. compacta) grows to only 12-24 inches. Perhaps you have the latter.

Varieties of this species, some variegated, are still marketed and planted in Minnesota. Fallopia japonica and Polygonum cuspidatum are two names for the same species. By either name it is a Minnesota Department of Agriculture Specially Regulated Plant.

In summary, it's legal to grow and sell this species in Minnesota but that may change if and when its invasive characteristics become intolerable.
