Thank you
@Sscape. I've been fighting it the last 2 years. Looks like my thickest planting of Geranium Rozanne and Striatum are winning the war by smothering it. But only on one side of my hill. I will just keep ripping it out, as I have been doing. Hopefully the Geraniums on the other side will help once the Striatum seedlings have matured.
