I have had difficulty with this plant in the Pacific Northwest. It does not fill out well so tends to be weedy and then when all the weeds are pulled it is leggy. I've moved it three times to different exposures, and finally just yarded it out. It never became aggressive for me, which I have heard can be a problem for others. Pretty little groundcover if it will grow in your area.
