Below is a quote from a garden forum on the web. I've lost the URL already !

I just read today in "garden west" magazine that there's a new plant developed
in Germany that's a natural dog repellent. It's called "**** Off" plant, coleus
canina. Developed by Dieter Stegmeier in Germany. I'm not sure who would carry
it in the States. /end quote

Has anyone information on the truth of the claims ?
